Hi idkwhattosay77,
Sorry to hear you’ve been unable to link your account for the past few weeks.
Since you’re currently playing as a Guest, please avoid uninstalling the game, clearing its app data, or switching devices while troubleshooting, as unlinked Guest progress may only be stored on the current device.
Please try the following:
- Update FC Mobile, Google Play Games, and Google Play Services.
- Restart your device.
- Confirm you’re signed in to the correct Google Play Games account.
- Clear the cache for FC Mobile and Google Play Games, but do not clear FC Mobile’s storage or data.
- Try switching between Wi-Fi and mobile data.
- Make sure your device’s date and time are set automatically.
