Amazing app, but glitches

This is an amazing app! Whenever I want to make a movie, its my go-to app. It has amazing features and is so much fun. But, I have noticed recently, that it glitches A TON. It always shuts down, screws up the audios, and makes weird black spaces between my clips. Its so frustrating. Please fix this. Thanks!
