messages in the cloud not deleting everywhere if deleted on Mac

Lol thanks for the extremely helpful advice; however, I my iCloud account is set up perfectly the same as it has been for the last five plus years that I have been using my MacBook. It wasn't until I made the terrible decision to accept this absolutely horrid Big Sur update that my messages stopped syncing properly. Luckily, after screwing around w/ it for over an hour I decided to completely clear and then re-sync my iCloud data to my MacBook.

Gotta say, I have been a pretty big fan of Apple for a while but after the last few updates I can definitely say that my next laptop will be a PC.
