I get a red screen with an exclamation point in the middle of it when I open a project on my mac desktop after filming on my iPhone. The red screen goes away after a few days, so I am wondering if this is an upload speed issue, or something else. I am not a video person and this is my first attempt at doing anything like this, so I may be doing something wrong, but I can't seem to find any instructions or tips that address the problem.
