Three times today, while sleeping, I received email notifications on new sign ins for my account from Italy and the US. This is the second time where something like this has happened. Songs are added and removed, music has also been played on its own before.
It first started shortly after I got premium. I've reset my password several times, logged out every several times, and now 3 "logins" in one day
For the record, I have never logged into my account anywhere but my phone and only this one phone, that being an s10+ with the latest updates
