All of the friends I have had have not vanished

Sometime last night all the friends I had have vanished from my friend’s list. I had roughly 100 friends.
Plex Version 3.31.1 Updated yesterday.

OS Centos 7

Did you recently pass on a device with a Plex app on it to somebody else?
Or did you have someone at home as a guest who had access to one of your plex clients?

Your friends were regularly deleted (by hand, one after another) from a device that was signed in to your account.
On Dec 15th, at around 4:45am GMT
it was a ‘mobile’ app.

No, This is very strange. I have now changed my password. Is there any way to restore/undo this?

No, unfortunately not.

I have now changed my password.

That is unfortunately of no use, if you don’t also tick this checkbox:

Do you have kids or a jealous partner, maybe?

I did that as well. Can you give me any other details like a location or an ip or device type?
