Mine has been doing the same and getting worse also keeps changing my settings to go in sleep mode every 30 seconds

My Mac Literally started tripping yesterday right after the update , Apple told me I should uninstall , but then what? lol

I had a crazy experience with my membership last year and had to got through a special set of procedures before I actually obtained membership . I recommend contacting the IT department and Im sure he will have it resolved, mine was a verification concern and the the fraud dept. had to handle something on their end, took 3-4 days to resolve and was only to contact me and I was only able to respond to them. hope this helps.

yes, Im not even able to use Safari anymore

this has happened to me 3 times, its most likely due to either conflicting information on file, nothing major, reach out to a Senior advisor and they will do a special arrangement for you and that will work , very detailed process. hope this helps
