App Store connect is not taking my app preview. I don't get any error messages. It just does nothing when I drag the file into the app previews and screenshots area. I also tried to use choose file and again nothing. The app preview was made per apple's instructions by recording in QuickTime and editing in iMovie. It's technical specs check out with the video specifications apple request other than it has no audio. Does anyone know if there is a problem right now with uploading app previews?
