PLEASE fix the audio and video glitches – iMovie Review

I’ve already written a review complaining about this problem though that might have been close to a year ago and I see many other people have this problem as well. PLEASE fix the app so it doesn’t randomly move the audio, video clips, and sounds that go with those clips. I’m making a Scarlet Witch AMV currently and already it’s done this about five times and I’m not even a minute into the video. It’s incredibly frustrating to deal with and try to move everything back where it was. This has happened with literally every movie I’ve made, more than once each time, even even if it’s just two minutes long. If you could please fix this it would be GREATLY appreciated.
