In June I bought a Garmin Forerunner 165. All fine until suddenly it would not upload some activities to Garmin Connect - say about 1 in 10. Everything else was synced, the step count, the body battery etc, they even showed the icons to show that I went for a run at 9am for example, but the run itself would not sync. I got fed up and returned the watch.
In September I decided to give it another go and bought another Garmin Forerunner 165. All had been going well and then today - same issue. My run will not upload, but it's visible as something I did in the body battery chart and the step count chart etc. Everything else is synced.
What is going on? Why can this watch not consistently upload activities? Am I going to have to return this one too?
