Matching Moments not Loading

I'm having similar problems and am using an Android. SN rescuebabe2002. Just now the recurring problem, when I receive coins from completing a task, then try to use them to buy five more moves, the game opens the shop window, and does not recognize that I have enough coins to purchase moves. I left the game and came back, and now those coins are gone. 

Also getting the overlapping in the cells occasionally, tho I'm not really bothered by it, as the game still works with it.
