Yeah this game has no medals resubmit functionality that I can find. That's especially bad when some of the medals take a very long time to achieve!
Do you know how grindy it is to get the Pro High Scorer medal only to have it *NOT* award on-profile due to some stupid medals connection timeout issue combined with zero medals resubmit functionality that is entirely the game's fault? Also I was cheated out of Pro Coin Getter due to that as well!
The game is 100% grind and very little skill.
