Failed to export Lightroom Mobile

Hello Adobe Lightroom, 

I recently purchased your subscription for the mobile app. I can't seem to export a video I edited with lightroom and it's a bit disappointing as I wanted to use this video for a post.

The video itself is a 22.2MB file size MP4. I'm using a Huawei P30 Pro. Not sure what else I can do to export this.

Can someone reach out to me and help?
