I have this same issue with all apps except Netflix. The "solution" I found is to restart the Roku after turning it on, but before opening an app (settings, system, system restart, restart). If I do this, the apps no longer kick me back to the home screen until the next time I turn on the TV/Roku. It's an annoying step, but worth it for uninterrupted playback!
I wonder if linking Rokus has anything to do with this problem. With a house full of Rokus, I don’t always see when other people are watching, and maybe somehow when one of my children closes a show and goes to another one, it maybe reverts my screen to home. Odd, but possible? Some people have mentioned that they have multiple Roku units. Is anyone running into this problem with just one Roku on their account?
The Express uses an IR remote, so if the remote for another Roku is within visual range it's certainly possible that they have accidentally controlled yours as well. But IR remotes require direct line of sight, and won't work through walls.

Good point. I didn’t think of this aspect, but I was considering the fact that while the rokus were linked on the same account maybe it could have caused a software glitch, possibly. Your point seems more logical, but they are definitely all in different rooms with walls and doors between them.
