Frequent hangs in the EPG Guide on TVOS

EPG Guide hangs when exiting a program to return to the EPG (using MENU button) about 20% of the time.

UI totally unresponsive.

I long press the MENU button to exit Channels and then close the app. I reopen Channels and go through the "Preparing the TV" process and all works fine again.

The hangs appear to be correlated to how how the programs/shows were running when I exit. Is there a background refresh going on for the latest EPG info that might be hanging?

NOTE: I am using the experimental audio feature with Airplay 2 support.
