How to show google play leaderboard on an android app?

So I followed the tutorials but it seems like it doesn’t work, am I doing that the good way ? or I should plug on the other nodes ? because I tried to launch the app in alpha on google play and the leaderboard don’t work

Same with the ads system, it doesn’t work in alpha, is that normal ?

HI. check this ue4 documentation for implementing the leader board. : Using Google Play Services Leaderboards | Unreal Engine Documentation

Im having the same problem but what I know is that you need some event for your Read Leaderboard Interger before it can work
