I don't know if I changed a setting or if it's an Android TV problem but I can't find anything to resolve it. When I select any app from the home screen I then get an option to Open, Move, or Favorite. Selecting the app used to just open it as you would expect.
Any ideas?
Well, that's the long-press menu. So, first see if your button is sticking on the remote. If not, did you recently install or update any apps that remap remote buttons?
