App Preview Stuck in Processing After Upload

While uploading app previews for our new version release, the upload completed successfully, but the previews remain stuck in the “Processing” state. The app preview video was created using the iMovie app.

I’m on macOS 15.3.2 and using Safari 18.3.1 to perform the upload.

Video details:

  • Resolution: 1920×886
  • Format: MP4
  • Size: 103 MB
