I have a MacBook and read how to fix a cookie issue. Quickly here's how:
Click Safari in upper left corner
Select Preferences
Select Privacy
Select Manage Data
Click on Celebrity (I just typed Celebrity into the search function)
Select Remove (not remove all)
Hope it helps solve some of your issues.

Another scary thing is stuff like Amazon Web Services (there are many others like it), huge Internet services shared by lots of websites around the world. It's entirely possible for one corporate problem to get pushed to places outside that company. I'm guessing that didn't happen in this case, but who knows for sure because that kind of thing almost never gets publicized. "IoT", the Internet of Things, get more mysterious every day.
Edit to add, sorry for the buzzkill lol . . . . .
