Apple Bricked My Gen 1 Apple TV
I've got a lot of Apple products, including three Apple TV boxes. The oldest one (Gen 1) had been sitting on a shelf for a few months since I moved a TV. Yesterday I re-connected it and it came up just fine. It showed that I was logged in, but some of my purchased content was not showing. I decided to try logging out, and then back in again. Unfortunately, Apple has now mandated 2FA and the Gen1 Apple TV does not support it. I phoned Apple Support and they informed me that 2FA cannot be removed from an account. This is a change they made a few months ago.
The upshot is this: If you have any older (non-supported) Apple products that use your Apple ID, they may get bricked in the same manner.
