(There doesn't seem to be an appropriate category for Authenticator so apologies in advance.)
I've been using Microsoft's Authenticator on my Android phone for a long time and it's been great. I have just upgraded my iPad to a 64 bit iPad and installed Microsoft Authenticator (it wouldn't install on my old 32 bit iPad). After signing in with my MS Account I was expecting all my 2fa accounts and codes to appear but they didn't. Have I misunderstood Authenticator's backup or is there an issue? I want the 2fa accounts and codes to appear on both devices so that if I lose one I have the other.
