I’m clearly doing it wrong because they just don’t seem to believe that they won’t be missing out on their regular programs, many of which they can also access on apps they already have. But they would rather keep watching DirecTV for $120 a month. I’m worn out
They are 77. I set everything up to run through the smart tv interface (I know I know, but it’s easiest for them). They use the TV remote to choose either the DirecTV input, or whichever app they want to watch. (The sound outputs via ARC to the audio receiver).
Perhaps using an aggregator like Plex to have all the app content in one place, rather than spread across apps?
You’ve already done all you can.
Maybe it’s more complicated then they want. Maybe they just don’t want to change. Not much else you can do.
