Android Google Play Games achievement unlocked popup

Hello everyone!
I'm having trouble with the achievements for the Android version of my game if someone can help me.

All achievements and all the functions of the google play service work perfectly, only the popup that does not appear.

I have all the resources requested to create the android sdk updated and working, latest version of the game make studio 2.

I researched a lot about this problem and I realize that it is something old that happens, but I didn't find anything updated about it.
