Hi, thanks for your response. I came across that article, and tried the "low hanging fruits; but I think this issue is different from a pure compatibility issue.
The app is (rightfully) complaining about missing Google Play services — that is not a bug since that is actually not running(and never was); so I won't be able to fix this without installing Google Play
However, the game is running perfectly fine in the background; So it is just a check that is not necessary for the execution of the app.
Steps 1 and 2 are already enabled for Diablo Immortal because it doesn't work without, I don't want to do step 3 for a game (also.. Google play would still be missing), I don't want to install Google Play store on my Phone and it is not a bug in the classic sense.
I thought that Graphene OS might be looking for annoying checks like that and just hiding them and that Google broke this function with a recent upgrade, hence why I figured "Development" was a suitable tag.
