TvOS 14.6+ App crashing / soft closing before 24 hours uptime.

Hi,

We have a narrowcasting app that runs for long periods at a time on TvOS 14.4 without issues, however after updating the apple 4k tv to 14.6 or 14.7 the apple tv 'crashes' before 24 hours.

This problem doesn't occur on a full HD apple tv.

The crashes aren't logged in our crash logging system (Sentry) So we don't think the App crashes it. We suspect the app gets closed by the apple tv after a certain amount of time.

Are there any changes in TvOS 14.5/14.6/14.7 that could be related to this issue?
