A. If your device is experiencing issues after an iOS update, try uninstalling and reinstalling the Rova app. This can help refresh the app's compatibility with the new iOS version. To do this, press and hold the app icon until it wiggles, then tap the 'X' to delete it. After that, go to the App Store and reinstall the app.

B. If the app still does not work properly, consider using an older version of the app if you have a backup. You can restore the app from a previous backup via iTunes or Finder if you have one. However, be aware that this may not always be possible depending on your backup settings.
