tvOS - Package problems - Image Asset - Plist Key

Hey there,

I currently have problems with packaging for tvOS so that the result can be uploaded to iTunes Connect. (App Store / TestFlight)
I use the most current version (4.19.2) of the engine and iOS is able to package fine and tvOS has no signing errors as well. My problems are the conformance to Apple tvOS App requirements you can see in the screenshot attached below.

Any insights as to how to solve one or multiple of these problems? In the project settings I can find zero settings about tvOS image assets. That is weird as iPhone and iPad can be configured seamlessly from settings.

The missing info plist key:
As we are doing a cross platform project I wish there would be a way that does not require manually appending it to the plist every time one wants to build for tvOS.

Another information I forgot:
We started with an earlier version of UE 4 so maybe manual steps are needed? I saw that since 4.12 some tvOS Image problems had been resolved.

same issue here, posted on forum…
