If the restore process takes a long time to finish

Stay connected to a reliable Wi-Fi network and a functional power source until the process finishes. The time it takes to restore from a backup depends on the size of your backup and the speed of your Wi-Fi network.

If you see a grayed-out app or one that takes a long time to load, make sure that you're connected to a Wi-Fi network. Next, tap the app to pause the process, then tap it again to continue. If this doesn’t fix the issue, delete and redownload the app.
