The "Account Error Number 0" has been preventing me from accessing marketplace since 1.14.0.2 Beta up till now. Error is occurring on both Android (screenshot 1) and Windows 10 (screenshot 2) platforms, and so far no effective solution has been found on Mojang support pages.
Additionally, while I can still log out of the Microsoft account on Android, the same log out button is not present on Windows 10 (screenshot 3).
