google play service problem with a game published in alpha mode

Hello All, I have an issue with Google play game service,i have an android game with GPGS integrated , i already published the game service , but my game is still published in alpha now when i reportScore from unity or ReportProgess to unlock an achievement , it doesn't update the game service , the score is not reported , the achievement is not unlock although , before i published the game service (it was still in ready to test phase) everything was working correctly and i was able to send score to the leaderboard.

so is it a problem that the game is published in alpha while GPGS fully published or i have an issue that i must solve from my side i didn't change anything in the code only published the game service i always find the score is sent as zero did you face this issue before?

thank you very much
