Please Fix! – iMunchies (Popcorn, Candy, Nuts) Review

This is a really fun app, but when I try to buy the extra snacks a white square pops up in the corner of my screen and nothing happens and I have to restart the app and it does the same thing when I try to buy again. This app probably hasn't been updated in 6 years and may crash a couple of times. So please fix it.
