Social on Android and iOS not working

Hello all,

I'm trying to use the Social API, but I'm getting a lot of problems.

On iOS I'm able to login, to report the score on the leaderboard and to see both the ac$$anonymous$$evements and leaderboards UI, but there is no way to show the ac$$anonymous$$evement banner even using the GK.

On Android I'm able to login but report score returns me alway false, don't know why because I am not sure if I can print an error code or message, and I cannot show the leaderboard UI.

For Android I'm using the GPGS plugin for iOS the Unity+GK.

The game has been published on iOS and Android but I didn't enabled the game services, I did it later enabling the ac$$anonymous$$evements and leaderboards in the features section on my App on iTunes connect and linking my App to the Google Play Game Services on my Console Dev. Not sure if t$$anonymous$$s could be related to the problem.

Any help? Thanks.
