First, make sure your device is connected to the internet and that you are signed in to a valid Apple Game Center or Google Play Games account.
Swipe Writer will automatically sign you in and display your achievements on the Home screen, either immediately or once it connects to the internet.
If your achievements still aren’t showing, try disconnecting and reconnecting your internet connection, then temporarily place Swipe Writer in the background and reopen it. This will give Swipe Writer another opportunity to connect to your account, sync your unlocked achievements, and check whether any achievements were unlocked while you were offline.
If you continue to have trouble seeing your achievements, please provide feedback here.
