I experienced the same issue, so I refreshed and the coins were there.
PRE-CLAIM: 5,493,601,222,541
WON: 4,100,000
Post-claim: STILL 5,493,601,222,541
I IMMEDIATELY refreshed the game, and my total increased by 4,100,000 to 5,493,605,322,541
So if you don’t see your total increase, refresh your screen and it should be correct.
