Hi,
You can push a swiftUI view only ONCE.
It seems the bug has been fixed since iOS 13.3 b4, but it is still present in the final version on tvOS 13.3
Also, i still have 4 open bugs in feedback assistant without any action since months now.
It look like Apple TV is the 12th wheel of the carriage.
It's very disappointing and i don't think to make another tvOS app, what a waste of time !!!
