Remote connection lost when leaving app

When watching live TV in the Android app while connected remotely the connection seems to be lost every time I leave the app. When returning to the app, I get a message saying no HDHomeRun detected. After a few seconds the app seems to reset and I can then start watching again by navigating back to the channel.

I don't switch apps often while watching TV, but I do turn off my phone screen during commercials to conserve battery and data. And when I turn it back on, the result is the same as if I've left the app.
