I have STARZ and I put the app in the third line of the main menu. Every other hour it resets all the way back to the bottom. HBOMax does this too sometimes. I hit * and go to move location and move it back to the top and again I go in and it goes back to the end. I tried updating several times and reloading, etc. Is there another way or am I stuck with a moving STARZ & HBO app channels. Have no issues with all the other channels.
It sounds as if it's getting removed and re-added. Could that be happening? Is there someone else in the household or with a device linked to the same Roku account that could be doing it?
