When submitting my App Preview, iTunes Connect says: "This video has audio that is not two-channel, no-surround stereo. Please refer to Apple's documentation for appropriate formats."
Well heres the catch, when I created my App Preview in iMovie, I deleted the audio track!
After giving up for a while, I came back and tried again, then I was receiving an error saying "file could not be loaded".
Each time I go to submit for review, my App Preview disappears.
Any ideas on how I can get my App Preview successfully submitted?

Click Movie button in the program. Under iMovie, click your movie project name, and you can preview the movie.
First off, is having an app preview video mandatory? No, it's not. And while including an app video in your App Store or Google Play listing doesn't directly affect your app's visibility in app stores, having an impactful app video can help increase conversion—which is a definite win!
App previews are short videos that demonstrate the features, functionality, and user interface of your app or game on your App Store product page. You can easily use a Mac to capture screen recordings of your apps on a Mac, an iOS device, or Apple TV.
The purpose of Xcode Previews is to back door in to your device effortlessly sandboxed while testing your own apps in real time as you edit them, this can also be done remotely . And that is a security concern .
For most apps that do not have the primary purpose of handling audio, I find background music or audio voice over to be a distraction in an app preview. If you want to add silence to preview, you can easily do it with ffmpeg:
ffmpeg -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=44100 -i preview.mp4 -shortest -c:v copy -c:a aac previewWithSilence.mp4
