Azure tenant lockout - help

Hi,

I'm experiencing the same issue described here: https://learn.microsoft.com/en-us/answers/questions/4373157/how-to-fix-access-to-a-directory-that-asks-me-to-a

I can sign in to Azure successfully. However, when I switch to my default directory (my personal directory, where I am the only administrator and the only user), I'm prompted to enter an authenticator code.

The prompt is asking for a 6-digit verification code, but the code generated by my authenticator app is 8 digits, so I'm unable to complete the sign-in process.

What's strange is that I can sign in to the Azure app on my iPhone and access my default directory without any issues. The problem only occurs when I try to access it through the Azure web portal.

Can anyone help me to resolve this?
