I have to correct myself. The zPosition of SKEmitterNode is not ignored, but calculated differently than on previous iOS versions. I still have no clue how to fix this. I don't know what exactly has changed.

Xcode 13.0 finally fixed the bug! One year I wasn't able to update the game. Now the SKEmitterNode appears in the correct zPosition again.

I'm employed by an LLC (actually German GmbH). When I use the form in App Store Connect, it seems to display my name and the name of the LLC. Is it possible to avoid the display of my name?
