Really? Really, Apple?

In general, its a good mobile editing app. Its simple, it has plenty of features, its free and doesnt have ads. But, it can be really, really bad and frustrating as hell. It can have a lot of bugs and glitches. But today I am more than frustrated. Today, this afternoon, after 8 hours of editing on a short movie project I had to present in class in 2 days, for Spanish, my iMovie crashes. After, I re-opened it. The app crashed again, so I opened it a thousand times but in the end it still crashed. I didnt know what to do. I spent 8 hours of my time without results. So, now, I have to edit again! Apple, can you fix the glitches and the crashes on the older versions of IOS, because ITS VERY F****** frustrating! THANKS IN ADVANCE
