Google is supposed to start cleansing starting Dec. 1, they are most likely testing some algorithm using AI, which is failing miserably. Better to backup your files, accounts before Y2K.
Thanks for info, Google seems to be very strict and unforgiving, I would better not to consider it then. I am just testing MS 365 Basic and after canceling the subscription, the incoming emails were blocked, but my storage was still available for the next 4 months. That is very important in case of any problems, that can clearly happen without user's fault.
