I am trying to backup my authenticator app entries to migrate to my new phone. When I try to "Sync Account", I get the error "Your backup is too large. Cannot save to the cloud." When I checked the free storage space available in my MS account, I have 4.99GB free.
I have tried creating a new account, and I received the same error.
I have 189 entries in the authenticator.
MS Authenticator v6.2310.7174
Android version 10 | Oppo ColorOS v7.1
