Dark screen when using Apple TV to synch music to my Hi-Fi

[Paulespot]

After synchronizing my device (doesn‘t matter iPad or iPhone, iOS 13 or 14) to my Apple TV - because this one is connected with my Hi-Fi - Spotify is only be displayed at the TV screen, the iPad or iPhone screen is dark. Even by ending synchronization the screen keeps dark. This issue occurred a few month ago and  is annoying.

My Question or Issue

Hi there @Paulespot,

Thanks for reaching out about this in the Community!

Could you try running a clean reinstall of your apps on all device. You can follow this device specific guide.

Also, make sure your TV is running the latest firmware update.

Let us know how it goes.
