Why does Apple TV 4K keep asking to sign into someone else's Apple ID account?
My Apple TV (which has been working fine for about a year) has recently started to ask to sign into my sister's AppleID account except that she is not a user of this AppleTV and I am the only user. (I also asked her if she ever tried logging on to the AppleTV and she denied doing so. Plus she probably has been in my house for 24 hours since COVID started) I even restored the Apple TV to factory settings and it is still doing that.
What's making it even more annoying is that it won't turn download Amazon Prime. It asks for my sister's password, and I click "Not Now", it says it can't download the Amazon app.
