Disfunctional and Ripped Me Off: Please Fix – Video Mixer to Combine Videos Review

I purchased this app a while ago...when I uploaded it off of my phone for 4 months and downloaded it back on. After having downloaded it back, all it does is crash and is full of glitches in which a video is uploaded, but then doesn’t show, only represented by an icon, which upon tapping brings me to an upload screen, and when I try to upload it, nothing happens, and when I attempt to mix that what I have the entire app crashes. When I go back to it, it is in the same state as it was before. I would appreciate it if you fixed these issues...
