Thanks! I think this needs a few tweaks before it's ready to merge though:

[bradenmacdonald]

We need something like the following:

Suggested change

	<Form.Row className="mt-3.5 mx-0 flex-nowrap" key={videoUrl}>
	// eslint-disable-next-line react/no-array-index-key
	<Form.Row className="mt-3.5 mx-0 flex-nowrap" key={`${index}-${videoUrl}`}>

Because otherwise there's a very weird bug when the URLs are empty or the same:

Weird.Bug.mov

Thanks! Please just make that last change ^ and then I'll merge this.
