"Streaming Channels" menu has disappeared from my Roku TV

I've had a Roku device for years and purchased a second one as well.  The original device was mediocre (original version had a design flaw) but the new one is great.  So, I bought a Roku TV and it worked great.

If I wanted to explore channels, all I did was access the Streaming Channels menu and I could see a whole bunch of channels (1000) for movies (I can't remember the exact path to it but it was the Streaming Channels menu).  I turned on the TV today and could not find the menu to get to the list of channels.  So I searched the web and, sure enough, many sites told me to access the Streaming Channels menu.  But it isn't there anymore.  So I went on my ROKU device and, it also has the same problem.  It seems that a new update has removed the Streaming Channels from my menu so I can't just go browse a whole bunch of free channels to see what's available.  I'm stuck with the ones I have saved so far which is alot but I liked being able to browse.

Is there any way to add the Streaming Channels menu back in?  Alternatively, how do I get to the same menu where I can see a list of channels (1000 of them) and scroll to see which ones I want to add to my Roku device/Roku TV?

Note:  I don't have a cell phone so no go on using the mobile app and the web store has just a few channels to add compared to the thousands on the Roku device.
