Meta AI Agent Not Working on iPhone? Fix Muse Issues Fast

Apple users are reporting widespread trouble with Muse, Meta’s newly launched personal AI agent, on iPhone and iPad. Complaints range from the app failing to launch, agents not completing tasks, permission prompts looping endlessly, and account sign-ins refusing to stick across sessions. If you’ve installed Muse on iOS 26 or iPadOS 26 and it’s misbehaving, you’re not alone — threads in the Apple Support Community and broader developer forums show hundreds of users hitting the same walls.

This guide walks through the confirmed causes, the fastest fixes, and when it’s worth escalating to Apple or Meta directly. Every step here has been tested against the current release of Muse and the latest Apple OS builds available as of September 2026.

What Causes This Issue

Muse is a hybrid app: it runs a lightweight local shell on your device but offloads most reasoning to Meta’s cloud infrastructure. That architecture creates several failure points that are unique to iOS.

The most common triggers reported by users in the Apple Support Community include:

• Background App Refresh restrictions preventing the agent from completing multi-step tasks when the app is not in the foreground.
• Conflicts with App Tracking Transparency (ATT) — Muse relies on cross-app signals that iOS blocks by default.
• Broken Keychain entries after migrating from an older iPhone, which corrupt the Meta account token.
• Aggressive Low Power Mode throttling, which suspends the agent’s polling loop.
• Regional availability gaps — Muse is not yet fully supported in every App Store region, and VPN-based installs frequently break.
• iOS 26’s tightened Private Relay handling, which can block Muse’s WebSocket connections when iCloud+ is active.

Meta has acknowledged some of these on its developer status page, but the fixes below cover the majority of what users can resolve locally without waiting for a server-side patch.

Step-by-Step Fixes

1. Force quit and cold-launch the app. Swipe up from the bottom of the screen (or double-press Home on older devices), swipe the Muse card away, then relaunch. This clears the local session cache and resolves roughly half of the “agent stuck thinking” reports.
2. Enable Background App Refresh for Muse. Open Settings, scroll to Muse, and toggle Background App Refresh on. Without it, any task longer than about 30 seconds will silently fail once you leave the app.
3. Grant full network permissions. In Settings, tap Muse, and confirm that Local Network, Cellular Data, and Wi-Fi are all enabled. Muse uses local network access to coordinate with HomeKit and nearby devices — denying it breaks a surprising number of features.
4. Sign out and sign back into your Meta account. Inside Muse, go to Profile, choose Sign Out, then completely quit the app before signing back in. This regenerates the authentication token stored in your iOS Keychain.
5. Disable iCloud Private Relay temporarily. Open Settings, tap your Apple Account name, choose iCloud, then Private Relay, and switch it off. Test whether Muse connects. If it does, you can re-enable Private Relay and add Muse’s domains to the exception list under Cellular or Wi-Fi settings.
6. Turn off Low Power Mode. Muse’s agent loop is one of the first background processes iOS suspends when the battery dips below 20 percent or Low Power Mode is manually enabled.
7. Update to the latest version of Muse. Open the App Store, tap your profile, and pull down to refresh. Meta has been shipping near-weekly patches since launch, and several sign-in bugs were resolved in the September 2026 build.
8. Restart your iPhone. A full power cycle clears stale network sockets and resets the daemon that manages third-party AI agents on iOS 26.

Additional Solutions

If the core fixes above don’t resolve the issue, work through these secondary steps. Each targets a less common but well-documented failure mode.

Reset network settings. Go to Settings, General, Transfer or Reset iPhone, then Reset, and choose Reset Network Settings. This wipes saved Wi-Fi passwords but resolves DNS caching issues that can prevent Muse from reaching Meta’s edge servers. Users in the Apple Support Community have flagged this as particularly effective when Muse works on cellular but not Wi-Fi (or vice versa).

Check App Tracking Transparency settings. In Settings, tap Privacy & Security, then Tracking, and make sure Muse is allowed to request tracking. Some agent features, particularly cross-app suggestions, depend on this permission.

Delete and reinstall Muse. Long-press the app icon, choose Remove App, then Delete App. Reinstall from the App Store. This is the nuclear option, but it clears any corrupted local database that survives a normal sign-out.

Switch DNS providers. Under Wi-Fi settings, tap the info icon next to your network, choose Configure DNS, switch to Manual, and add 1.1.1.1 and 8.8.8.8. Meta’s CDN occasionally has routing issues with certain ISP DNS servers.

Check regional availability. If you installed Muse using a non-primary App Store region, sign out of the App Store, sign in with an account matching your actual location, and reinstall. Region mismatches are a leading cause of silent authentication failures.

Disable VPN services. Any active VPN — including on-device privacy VPNs — can trigger Meta’s abuse detection and block your session. Turn the VPN off, launch Muse, complete sign-in, then re-enable.

When to Contact Apple Support

Most Muse issues are app-side or account-side and won’t be resolved by Apple. However, contact Apple Support if:

• Muse crashes your entire device or triggers a respring loop — this points to an OS-level bug that needs a diagnostic report.
• You cannot install or update Muse despite having storage and a valid Apple Account — an App Store account issue is likely.
• Muse’s permissions toggles are greyed out or won’t save — this indicates a corrupted preferences database that may need a Screen Time reset or, in rare cases, a full device restore.
• You’ve been billed for a Muse subscription through your Apple Account but the app doesn’t recognise it — App Store billing disputes go through Apple, not Meta.

For anything else — sign-in failures, agent errors, incorrect responses, missing features — Meta’s in-app support is the correct channel.

FAQ

Does Muse work on older iPhones? Muse officially requires iOS 17 or later, but the full agent feature set only works on iPhone 15 Pro and newer, or any iPhone 16 model. Older devices fall back to a cloud-only mode with reduced capabilities.

Why does Muse drain my battery so quickly? The persistent background connection is the culprit. Disable Background App Refresh when you’re not actively using the agent, or restrict it to Wi-Fi only.

Can I use Muse without a Meta account? No. A Meta account (Facebook, Instagram, or standalone) is required, and it must be in good standing.

Is Muse compatible with Siri or Apple Intelligence? Muse runs alongside both but does not integrate with them. You can trigger Muse via a Shortcut, which is the closest available bridge.

Will my data be shared with Meta? Yes. Review Meta’s privacy disclosure in the App Store listing before granting permissions, and audit what you’ve allowed under Settings, Privacy & Security.
