Waste of time

I played this game for 6 months，always login with my google account and suddenly someday it tells me “Unable to authenticate，please try again”. So I spent hours tried over 200 times to login yet nothing changed. Ive never hacked or doing anything unusual. Unable to login=lose your account=everything you have done before was waste of time. What a junk！
