Sugar Drops Reward Page Freezes

I reached the level to get a sugar drop rewards but when it gets after the parcel drops the claim reward button does not light and I have to exit the game and reboot my phone to get back to the game. I can then play again and collect more drops but it all just freezes up again on the reward page when the game is over.

I see this has happened top others but that question is marked as solved with no solution presented.
