How can I approach this? Photoshop for the receipt

They'll most likely cross-check Its authenticity.

Although It's a lengthy and arduous process, you're better off using the corrupted file method.

and upload a corrupted video file? I have no back up for when they reply with something like "Could you upload your video to YouTube or Google Drive instead?"

As per their response below, they've stated "If possible", which suggests It's not a necessity.

If possible, could you please provide a video showing the problem that you are encountering?

Will do that. Thanks!

You're welcome.

We shall await the latest developments.
