Spectrum remotes stopped working with TCL TV

UPDATE 2 hours later, I had given up after trying a ton of codes and anything else that had been posted by others and walked away from the TV with the volume and power still not working.  Then magically somehow they started working again.  I would really love an explanation to this because it makes no sense.  The tvs factory remote worked the whole time, just not the spectrum remote.  Both are IR, and then it starts working again with the spectrum remote?  As an IT pro who has been in this space for decades who also does a ton of consumer electronics on the side this doesn't add up.  I really wish Roku would provide some clarity on this whole mess.  Don't get me wrong, I am very happy(because my wife is happy) that it is working again.

Spectrum guide remote no longer controls power or volume on my TCL Roku TV.  Worked yesterday, TV got an update this morning, now remote doesn't work.  Clearly an issue with the update.  Tried all the codes suggested, tried all the manufacturers suggested.  Checked several places other than here.  No luck.  Please fix the update and revert whatever changes were made related to IR.  And have Spectrum ads the correct codes for TCL TVs to the TCL entry in the on screen remote setup.

TCL 50S421

12.5.0 update as of 9:28 AM, Spectrum Guide remote no longer controls volume or power after that. 

If you knew that people were obviously having issues, why didn't you pause the rollout until you had a fix?  In 2023 I can't believe we are even having to deal with problems with IR remotes.  I have just wasted the last 2 hours trying to fix my volume control and power button that was working yesterday and your update broke.  Unacceptable.
