My situation :
Google Play Games works well when I test it directly on my device (with Android Studio direct generation) With this configuration, all the workflow is ok.
I am now in alpha/beta testing I generate with Android Studio a signed APK and i upload it on the Google Play Console. My application and my Game application are both published and i am with other people in test emails. But when i try to sign in to Google Play Games, i get the error 10004 which correspond to RESULT_APP_MISCONFIGURED.
I checked and i think all is ok :(
Could you give me ideas to resolve this issue ?
