A. Clear the app cache to resolve any temporary data issues. Go to 'Settings' on your Android device, select 'Apps', find Fitdock, and tap on 'Storage'. Then, tap 'Clear Cache'. After clearing the cache, restart the app and try syncing again.

B. Ensure that your device has a stable internet connection during the sync process. If you're on Wi-Fi, try switching to mobile data or vice versa to see if the sync issue persists.
