App Crashes After Purchase – VidClips - Perfect Movie Maker Review

I just paid to unlock all the app add ons including speed because I want to reverse some of my clips. Everytime I attempt to access anything other than adding a new clip, the app crashes. This has happened repeatedly (I’ve opened and closed the app, turned my phone on and off, etc) and is making this feel like a big waste of money ??
