Setup is an ATV4k feeding through a receiver and into a 1080p TV.
Yesterday I first started streaming music from one of my local computers using the “Computer” app on the ATV4k (connected via wifi), then fired up Zwift. The app ran fine, but hung/crashed every time I tried ending a ride and either saving it (to Strava) or deleting it. I was able to exit the hung Zwift app by holding down the menu button on the remote. Restarting the app led to a blank screen and another crash, but it was ok after restarting a second time. Same thing happened today, multiple times, so it was not a one-off. I did note that my data did get saved to Strava properly, but the crashing is still a pain.
