Hey @daisylira,

Opposed to automatically syncing to Strava, it may be beneficial to export a GPX copy of your activity and upload it manually:

1. View the activity history, find the specific activity and view its details.


2. Swipe left to access the 'more' screen


3. Tap export


4. Finally, connect the watch to a computer and download the file(s) find the imported file in the GPX date folder.  /sdcard/gpxdata.


5. Then upload the file to strava.com/upload/select

I hope this helps!

Hi

thank you for your reply.

I have just uploaded a workout using the TCX-file but unfortunately the moving time is still different / lower than on the ZEPP app.

Hey @daisylira, 
Sorry for the trouble. If this is still an issue, please go ahead and disconnect from the application and then try reconnecting. You can disconnect from any third-party applications here:

You can also try our initial troubleshooting step of deleting and reinstalling the Strava app. Our recommended instructions are below:

1. Delete the Strava application from your phone
2. Power your device off for 10 seconds
3. Turn your phone back on
4. Reinstall the Strava application 

Note: You will not lose any data if you do this since all data is stored on the Strava servers.
