I developed a game for Android with Unity3d. I am using the latest Facebook Unity SDK (Version 5.1).
The game is NOT published on the Google Play Store, yet.
I want to release it soon and I want Android to be a listed platform in the AppCenter.
For some reason I can not switch it on. It says: "This platform cannot be listed because it is either configured incorrectly or not supported in App Center". I also created it as a canvas app. I can switch that on!
Is this because:
a) The Facebook Unity SDK is not support by the AppCenter (https://developers.facebook.com/docs/games/appcenter/guidelines states that an Android App should use the Facebook Login SDK for Android, see "Eligibility Requirements")
b) The App is not published on Google Play.
c) A wrong configuration. What could this be? I filled in every possible box and uploaded the needed screenshots.
d) something else?!?
Thanks in advance!
I got problem solved with enabling single sign on in settings->basic->android.
