Hey @HummerDmaxLee,

The next troubleshooting step to try is to export a GPX copy of your activity from zepp and upload it Strava manually:

1. View the activity history, find the specific activity and view its details.
2. Click the three dots in the upper right corner.
3. Tap Export track
4. Click GPX format to start the export. Exported files can be found /storage/emulated/o/Zepp/gpx.
5. After exporting the file you will see a red Share button, click this to send the file to yourself or navigate to the location noted above on your phone.
6. Then upload the file to strava.com/upload/select

I hope this helps!
