Was fun, but now crashes at start of every game!!

Im only playing the free version, but after passing all the levels, it started crashing so much it is impossible to rank up levels that had bronze or silver stars. In fact, all levels will crash right after "game on" shows. It starts stuttering as the game scrolls through the course, then just crashes. Usually before a ball can be launched!!! Too bad, but it is what it is. (iPhone 6s, OS 9.5)
