I am trying to restore Authenticator on an iPhone 7. This iPhone has been restored from an iCloud backup of my old iPhone 7. Both are running the same version of iOS, 14, version 14.5.1. When I open Authenticator & sign in to my Microsoft account the restore/recovery starts, then less than a second later the app crashes & I’m back at the iOS springboard. When I open the app some of my accounts have been restored, but not all of them. Quitting and re-opening the app does not make any additional accounts appear. I’ve deleted the app and downloaded it again, but the crash happened just the same. What do I do?
