Something funky was going on the other night through today. Someone enabled some shows they weren't supposed to or something. My daughter messaged me saying the walking dead, Grey's anatomy and a bunch of other stuff was on Disney. There was even a section labeled 'Star' with lots of new content but it's all gone as of right now.
My brother and I share an account. Awhile back we were having an issue where every time one of us got on, the language was set to Spanish. We each thought the others kids were doing something stupid, but after a little bit he I guess figured out someone in Mexico had got his account info. So maybe try changing your password.
I'm using a VPN so I thought maybe it switched to a South American country or something. I manually switched to one to test it out but I didn't get any of the content back and I didn't get the section that said Star.
