Correct settings could not be determined

I have been using eM Client for a few years. I like it a lot.
I have just installed in on my new laptop and I’m adding my email accounts. I have successfully added accounts from from one of my O365 tenants successfully. However, when I tried to add accounts from my other tenant that has MFA enabled, I am getting the “Correct Settings could not be determined” error. Now, when I added the accounts from the other tenant 1 I had to validate and approve access for EM Client to my account. I’m not getting the option with tenant 2.

It’s pretty obvious it’s a difference in the configuration of the MS Tenant account, but I can’t find the difference. I am admin on both accounts. I do have to use the MS authenticator when logging directly into the tenant with the same email accounts.

Any help is appreciated.
