App keeps crashing

In the last week or so, the ATV app works fine, but if I navigate to the ATV Home Screen and then go back to the app it hangs. I get a generic blurry screen and after a few seconds it disappears and I’m back at the Home Screen.

Opening the app again works after the whole ‘preparing tv’ view. It’s like there’s a problem with the app going into the background and / or not restoring properly from being in the background.
