Previously (before ios12 or Sep 2018) my Apple TV 4k remote control will turn on my Samsung TV, suddenly it stopped working, can't seem to make it work again. The only thing changed I believed is the update of ios on AppleTV. Any help is appreciated. Thank!
Apple TV 4K, iOS 12
Found the issue. I do not know the actual reason but our cable guy unplugged the power to the TV (not just turn it off using remote), and the AppleTV remote is working now - he mentioned something like "HDMI handshake problem".

Check the HDMI-CEC setting:
Apple TV: Settings﹥Remotes and Devices﹥Control TVs and Receivers﹥On
Possibly the update had reverted some setting?
Check TV settings and if there is an update there as well. Ultimately, issues with CEC are dependent on the TV
I have the same issue with my Samsung TV since upg to the latest version of the OS. I have checked all of the setting and they are correct.
Above still applies
I have the issue with two different ATV4's on two different displays. One is a Samsung TV and the other is a Panasonic Projector. Both worked fine before being updated to IOS12.
