Windows 10: Why is Microsoft Authenticator Stuck in a Login Loop?

I'm having trouble signing in to my Microsoft account using Microsoft Authenticator on Windows 10. I also use Microsoft Authenticator on my Android phone.Here's what's happening:When I attempt to log in, I receive a message that says, "We'll send a sign-in request to your phone to sign in with my email address."I click the "send notification" button on my computer.On my phone, I'm asked to tap the number displayed on my computer screen to sign in without a password. I do this, and it confirms the number I selected on my phone is correct.However, back on my computer, I get stuck in a loop with

Windows Microsoft account authentication

I have a valid Microsoft account and a Windows 10 PC with Hello/PIN account login enabled. I also have the Microsoft Authenticator app installed on an iPhone and configured for the Microsoft account. Additionally, I have two step authentication configured
for the Microsoft account. With all of that said, I have become very exasperated while trying to unravel the various authentication paths (and their security implications) through this multi level login security scheme. I find the associated account security
documentation to be woefully inadequate. Thus, I would like to pose the following list of questions for starters.

1. Does Windows Hello/PIN amount to a two step verification login procedure for my Microsoft account?

2. Does approving a Microsoft Authenticator login attempt (without two step verification explicitly set up)

amount to a two step verification login procedure for my Microsoft account?

3. Does approving a Microsoft Authenticator login attempt (with two step verification explicitly set up)

amount to a two step verification login procedure for my Microsoft account?

4. If answers to both 2 and 3 are yes, then what does explicit set up of two step authentication do?

5. Does a coherent, comprehensive document explaining Microsoft account security configuration exist somewhere?

6. If the answer to 5 is yes, wherer is it?

Thanks in advance.
