Great app, if it werent for the crashes

I made a project recently in this app that required only one video and some copying and pasting. Creating this project was quite easy and intuitive with the Green Screen apps great controls. However, trying to access this project at a later time to export it has caused the app to crash everytime. I have tried creating new projects and redoing the green screen effect and nothing seems to be working. If Do Ink fixes this I will write a better review with more stars because I think this app can be better if the developers put in some time to work out the bugs. Thanks!
