I have noticed from time to time, my watchlist will have random movies appear that I know for a fact haven't been watched. This usually happens every few weeks or months, and every time I unregister the devices on the account and change the password. Today I did the same thing and changed it to a password that I've never associated with the email the account is attached to and it happened again the same day barely 2 or 3 hours later. Is this a known issue or are there any workarounds for this?
