Hi,

I am experiencing the same with my Amazfit Balance which is not syncing my swim sessions to Strava unfortunately. 

Please note it is registering and available in the Zepp application, however just not syncing to Strava.

Could you please share an update on the status of this issue? 

Kind regards,

Rik
