so i have made two games with unreal engine (BLUE PRINT ONLY) for android which are published and has already set achievements and leaderboard in google play.
Problem is when player unlocks achievement, it popups "unlocked achievement" and also it update in play games and google play app shows all achievements which are unlocked but temporary. So what's happening is i can unlock achievements, achievement popip shows, play games update achievements and after some time (about 30 min without playing game or opening game) all achievement locks again automatically. And it is happening in my both games. I already checked my all codes are ok.
M i missing any api or permission ? or it is problem form google ?
