Source/ input button!

[Sumbl1ss]

It’s been said a few times. I had my one remote for the pvr for awhile. I got a new box 2020, new remote. Now when it’s fumbled or slides off the couch, buttons are pressed. That was super annoying, I don’t know why it’s more sensitive.
But the new tech last week, programmed the remote to the tv (now it handles volume) but I can’t change the source. I do this several times daily, I still need the tv remote. I can’t even find it in menu, it flat out doesn’t exist! It can go right above the On Demand button!
