@Burrows20 , Someone else reported not having the hide-all option (or it didn't hide the new streaming channels). I looked back a few pages and that thread didn't jump out to me. But, I'm positive I've seen this at least once before. You're not the only one.
My antenna tv experience was ruined by the 9.4 update. I found that doing a factory reset (but telling the initial setup I don't have internet) installed what appears to be an older version of the software. (No 1000+ steaming channels. Favorites worked again. Continuous channel changing worked again.).
Looking back at how long this disaster has been allowed to continue, that might be your best option. If you use Roku for streaming, just spend $22 on a Firestick Lite, and stream through HDMI. Basically, turn your too-smart TV into a dumb TV, and be done with it. Not as elegant as a "do it all" TV. But, it's not doing it all very well. So?
I've disconnected both my tvs to protect them from further untested updates. Initially, I thought the no-network (basic) software was something embedded in the tv. Something I could always get to as a last resort. But, forum user sksR said he believes it's being updated too. To me, it doesn't look anything like 9.4. So, I didn't think it was. But, if it is 9.4 and subject to further update, then it's worth keeping in mind that you might lose the ability to get back to that level of functionality. (I.e., I'd think twice about connecting to the internet again if you do this. You might not be able to get back to this.).
Just an option worth mentioning. It's not elegant. Multiple remotes to deal with. Lots to dislike. But, for me it seems like less to dislike than what we're having forced upon us.
"People are often amazed at how much we’ve done with the number of engineers we’ve got." (Roku CEO Anthony Wood, Austin Statesman, Oct 4, 2019). "Amazed" is one way of putting it.
