This used to be my favorite but no more

I absolute loved the prior version of this app as jigsaw puzzles are something I love. Unfortunately, when I purchased my new iPad Air2 and my iPhone 6+ this app went in the toilet. The shapes of the pieces are no longer like a real jigsaw puzzle and pieces disappear or lock onto the screen way outside the puzzle. I am sooooo disappointed, I want the old Jigsawed back. Please fix this issue, give us the old version back.
