Hey there. My apologies as I must have misunderstood some of the acronyms involved. In short, before the latest update, my Panasonic TV remote worked fine to control playback, menu and volume functions on my Apple TV. The same goes with my Yamaha receiver remote as well as the TV remote for another tv (can't remember the brand).
We have been controlling our Apple TV's for years with the remotes that came with the devices we have them connected to.
Nothing has changed with all three devices. The only thing that has changed is that the Apple TVs have updated and seemingly removed that function.
I have reset one of them completely to no avail. I have checked all of the Apple TV settings that I can see are related as well as confirming no configurations have changed on their respective connected devices.
Honestly, it's not a huge deal as yeah we can use the little Apple TV remote, but over the years we have just preferred using the bigger remotes with normal buttons :)
So frustrating as they ALL worked flawlessly for ages, and all three have just stopped.
I know I can get the Apple TV to "learn" those remotes, but if we try to control the TV in any other way (like just watching free-to-air tv or use another device), the learned functions still get sent to the Apple TV......this could cause a bit of havoc and even lead to unintended purchases or whatever. So that's not a viable solution.
I guess I just wanted to see if this is being experienced by others and perhaps a known issue that Apple will address in a future update.
