Please CHANGE THE FOLLOWING

iMovie was very good. Notice how I said was. I dont know what happened, but now it absolutely ruins my videos. I add music, its too loud. When I change the volume, I have to exit the app and re enter. When I put a transition in, it has a two second black screen at the end of each clip. When I add a video, its automatically muted. When I apply a filter, it flickers. And talk about the frame quality! It cuts off my face in every video. I dont like IMovie anymore, but I am not paying for an app, nor will I use an app with watermark. So Im stuck with it. Just make it work, please. Especially for the users who did pay for this.
