When I put infuse into the first column of tvos,If you open it after a period of time after shutting down, infuse will automatically run to the end of the screen software.

HI.
I have the same issue with the CANAL+ app (Canal+ is the French HBO), which I put at the top right position, and sometime moves to the bottom right position of the app grid.
The position of an app on the Apple TV home screen is actually handled by the system, and if you are using the One Home Screen feature on the Apple TV changes made on one Apple TV will sync to others.
If you are seeing issues outside of this you can try restarting the device or maybe even perform a factory restore to see if this helps.
