My Apple TV keeps popping up to verify Apple ID
No matter what I do, or how often I put in the password and it is accepted the Apple TV keeps asking for the password again within a few minutes. With the more recent update(s) there is a red dot with a two for my apple ID and it says an iPhone is Required to update my apple ID setting and another button also says use an iphone to "Finish signing in. I do not have an iphone or other iOS device and it shouldn't be a requirement for this standalone device!
I bought my Apple TV brand new and have only ever signed in one ID ever. I have chatted with support but they don't know what to do either. I'm supposed to get a call from a senior tech tomorrow but I have been trying to get this resolved with apple support for years.
How do I clear this error?
