Microsoft Authenticator Wrong Codes

A while ago, I changed my phone and switched from Android to iPhone. During the process, I installed Microsoft Authenticator and transferredall of my accounts.

I can see the six-digit authentication codes beinggenerated, but whenever I enter them, every service says the code is incorrect. My phone's date and time are set to update automatically, sothere doesn't seem to be an issue there.

I need to resolve this problem because important accounts, such as GitHub, are protected withMicrosoft Authenticator.
