My family uses IOS and Android Minecraft Bedrock.
My profile is assigned to my Microsoft account. I can authenticate with 2FA ok to my Microsoft account. But nothing happens. My profile is empty and marketplace tells me it can’t connect to internet. I tested my IPad and my Android smartphone same issue. My son’s account profile still works. All is Setup as Microsoft family account. I wiped my IPad to have a clean IOS 14.6 but problem is still the same.

Install of Xbox app, login to my MS account and doing some not relevant changes to proof my account is okay solved my issue.
hopefully this helps other users also
regards
Daniel
