Hi there. Sorry to hear you're having trouble logging in. Please first make sure the date, time, and region settings on your device are set correctly and set to update automatically if possible. Incorrect settings can sometimes cause login and authentication errors.
After checking that, please try the following:
- Close FC Mobile completely and reopen it.
- Switch between Wi-Fi and mobile data to see if the issue persists.
- Clear the FC Mobile app cache (Android) or reinstall the app if you're on iOS (only if your account was linked before) .
- Sign out of and back into the Facebook account you're using (if applicable).
- Restart your device and try logging in again.
- Test it on another network or device if possible
