IMovie for iOS 2.0 export doesn't work. Anyone else have this problem and how do you fix it?

Question

It seems that I can export projects that are very short (less than a minute) but anything longer than that simply shows the export progress bar and then never makes any progress. I've left it sitting there for an hour and it never moved. This also means I can't upload anything to YouTube. It was working fine last week when I exported a five minute video in 1080p, but now I can't even export a three minute video in the lowest quality option.
I'm using iMovie 2.0 on my iPad and iPhone and the issue is present on both devices, even though it was working fine last week.
I have already uninstalled the application, reinstalled it, and it still won't export any of my projects.
Oh, and Apple removed the ability to open iMovie iOS projects in iMovie for Mac because that feature made way too much sense.

Answer 1

Then you should provide the information requested by lllaass so that people have information on which to base a diagnosis. I'd suggest you start a new topic with your issue (use the "Start a discussion" link under the Actions header at the upper-right of each main topic page). It's generally better to ask a question as a new topic rather than as a reply in someone else's thread. It's more courteous to the original poster, and is more likely to get your question the attention it deserves.
