Google play games deleted many game ID associated with Google account which resets all game progress from Google servers and also gamer experience level (xp) with all achievements may be due to fair play policy of many realtime games.

This move removes all progress that any user gained by investing valuable time over years and also money with in app purchases.

Google must provide back their game accounts(ID) otherwise it affects so many users to start all over again and they leave it all with broken heart as it is very boring to start from ground which is already done years before.
