The title says it all. CEC has not worked since the latest update. My LG tv has not been updated recently. I hard rebooted both devices with no joy and switched CEC on and off on the TV (why doesn’t the Apple TV 4K have a switch for this that’s clearly labeled?) with no change.
Also, still no frame by frame or slo-mo on TV 4K. Is there a reason that this can’t be done?

That's the same time frame. I finally had to restore the Apple TV. Thankfully, iCloud remembered my apps and their arrangement and the "new" system for logging in to all of the streaming apps is much easier these days with the use of QR codes and the iPhone camera. HDMI CEC now works again.
It's not worth chasing this thing as there is no easy fix. I suggest you do the same and just reset the Apple TV. You will be back up and running in 30 minutes.
Good luck.

On Apple TV, CEC can be activated through: Settings﹥Remotes and Devices﹥Control TVs and Receivers﹥On.
What functionality of CEC is not working for you? What did you expect that didn’t have the wanted behavior?

then that would be something that would be up to an app to implment more than a global feature
but if you wish to suggest apple add the feature to their you can use their feedback channel
I verified that the TV is not the source of the problem with CEC as the DVD player I have turns the TV on with no issues.
The Apple TvOS update definitely broke HDMI/CEC.
Yes, that feature is well hidden in plain sight by trying to "dumb it down" for the average user. Sometimes, a thing should just be called what it is. ;)
Up until a couple of weeks ago, when I turned on the Apple TV device, it also turned on the TV (which has not had an update recently, unlike the Apple TV). Inversely, if I turned the Apple TV off, it would send a signal to the TV and that turned off too. This feature just stopped working.
I did a hard reboot on both the television and the Apple TV and toggled the switch in each as well with no joy.
I'd rather not do the standard "tech support script" first step of resetting the TvOS and lose all passwords and customizations with the possibility that the issue was indeed in the update and would still be there. That is the absolute height of frustration, as I'm sure you will agree. I believe that the recent update broke it and will wait to see if the next one fixes it before nuking the device. The first suggestion from Apple Support and, recently, MS support as well when I sampled Windows 11 was just that. Heck, I could do "tech support" for either if that is the go-to fix for everything. At least Windows 10 was backed up. There is no such easy option for any Apple device other than their PCs.
Regards and thanks for replying.
Yes, mine worked fine until the latest update. I dread resetting it with all the passwords and customizations to fix this one niggle. As stated, the Sony Blu-Ray player I have does turn the TV on.
Apple hasn't offered slo-mo or frame-by-frame in the new remote. It's a bit silly to sell full-length films without that feature when I can get the DVD or Blu-Ray for the same price or less.
I have a Samsung TV. Has worked for years with my Apple TV for TV On/Off via HDMI CEC. Stopped working about a month ago.
And they did it again with 17.4…
I can confirm, Phillips TV and Apple TV OS ver 17.4 and CEC stopped work…
HDMI CEC broken TvOS 16.4
