Hello all,
as I've observed that this issue is causing only on my private device and my private account, I assume it's not related to MS Business accounts.
For the moment I'm not facing this issue anymore, after the removing of my password from my private account.
That means I switched to passwordless authentication only.
How to go passwordless with your Microsoft account - Microsoft Support
I don't know if it is really a solution, nevertheless it could be a try.
And to be honest, who is needing passwords today? ;-)
Greetings
Mario
