Apple TV does not update automatically even when set to do so.
I am currently attempting to install some Meross Homekit devices and I am troubleshoots some issues with a "No Response" issue from these devices. I saw some feedback that indicated my Apple TV (acting as Hub) may need update. I checked and it did. Update completed. However the purpose of this question is this has been an issue every time even if I have Auto Updates selected in the Apple TV System settings. This is not a recent issue but ongoing. You forget about it since you just updated it but it catches you when something else does not work. It is not that I "Need" new features but I do need fixes when they affect other integration. Guess Apple would say "Sorry we did not test that" understood, but someone is saying not my job!
