Lately, it's not always saving the last piece or two - frustrating! I'll end by finally finding a piece and I close the game to do something else. I reopen it and the piece I KNOW I had put in is gone. Last night, I finished the left side edge of a new puzzle. This morning, that edge was not completed and several pieces were still scattered. I get it when my cat jumps on my real puzzle but this is digital so why is it no longer saving my progress?????
