The problem I had been having with the Home screen being gigantic after opening Prime and/or Netflix app is resolved. Maybe because I am on a new update. However, now if I open Prime and exit out, then try to open Hulu, it won't fully load, It starts up but then backs out again to the home screen. Same with HBO Max. If I restart to device they work again. But that means I will have to restart my roku everytime I use the Prime app.
