Hello,
yesterday Garmin Connect App was updated to version 4.15 on my mobile phone (Huawei p10 lite). Since this Update Garmin Connect App will syncronisize with my Fenix 3 HR but syncronisation of activities didn't finished. Syncronisation of heartbeat, steps, notifications etc. works fine, only activities can not be syncronisized. With Garmin Connect on my computer it works also for activities
Best regards
Markus
