@Em0nM4stodon Today's example.
My wife got told "your Microsoft subscription has expired, you can't use Excel any more".
I had, of course, paid for the subscription to continue for another year.
BUT ... I'd jumped through all the multifarious hoops necessary to refuse the vast hike in price in exchange for having my PC polluted with AI bollocks. Which seems to have counted as cancelling my subscription and creating a brand new one. Thereby losing the family members who were attached to the "old" subscription.
It might be time to find out whether any of the free Office substitutes are yet good enough to use. (They weren't a while back, when all of our children in turn (a) said "I'm not using nasty Microsoft", and (b) downloaded some open source Office replacement, and (c) in due course came to us and said "Mummy Daddy can I have the real Office please?" Something to do with needed to be able to interchange files with the school so as to be able to do their homework.)
