Why isn't google developers game services working?

In order to get ads The info I need is on google play developers->Game services->Xapp
But the problem is that even though I uploaded my game it’s not showing up on game services. Only on all applications. Did I do something wrong or what.

That’s where it talks about ads.

Also What is the game services tab? I’m extremely confused. It says I can publish the game under game services and I already published it under all applications.

I don’t know if this is related, but you need your apk signed in order for google services peopely work with you application, here instructions how to do it:

Ok Thanks, that thread helped. I kinda get what it all means now thanks! :slight_smile:
