Other than OTA tuner software on one of my Vizio TVs that became dogshit slow after a firmware update (which prompted me to just buy and use a cheap Mediasonic Homeworx tuner box) and the Apple TV app on another TV, I’ve never used any other built-in smart TV app more than once. If nothing else, they are always horrendously slow to the point that it swiftly becomes an exercise in frustration to use them.
