App Previews uploaded to iOS Previews and Screenshots in App Store Connect fail to process

Uploading video files as App Previews get stuck in "The video file has uploaded and is processing". I have had two video files in this state for 24 hours. I have uploaded JPEGS and they upload and process instantly. I have confirmed that video file is the correct resolution, size, etc and plays on my machine.

Anyone know how to overcome this? I have created a report here: https://feedbackassistant.apple.com/feedback/13694393
