If you have the Mobvoi App authorized to sync with Stava, you can actually export your GPS trail through Strava. It's a little bit of a workaround, but I've done it successfully. I was checking GPS accuracy and discovered it almost by accident.
From the Strava website, open your activity and click on the three dot menu to the left of your activity. There's an option for "Export GPX".
