What to do
- Confirm both devices are logged into the exact same account.
- Check the app's sync setting and make sure it's turned on, not paused.
- Confirm both devices have an internet connection.
- Force a manual sync if the app offers a 'sync now' or pull-to-refresh option.
- Update the app to the latest version on both devices.
- Check storage space on the device that isn't receiving updates.
- Log out and back in on the device with sync problems.
When to call a pro
If sync stays broken across every app for a particular account, contact the app's support, since it may be an account-level sync issue.
