I have Vivoactive 3 running SW Version 3.50, GPS Version 4.40; mobile is Moto G5 running Android 7.0, GCM 4.6.4.
Sorry about these apparently total newbie questions but I'm getting increasingly frustrated with my Vivoactive 3, a device that I really do like, but...
Up to a week or two ago the v3 sync'd ok with GCM on the Moto, just occasional issues.
Recently I'm finding that viewing the My Day display, which is set to show Steps, Floors, etc; I then tap through the Steps count to the Step Details (or Floors) screen. Previously that was updated from the My Day screen. For the past week or so it no longer updates after syncs, saying No Data Available.
If I connect the V3 to my PC and start Garmin Express and let it sync to GE the Step Details screen and the Floors screen immediately update. It the moment that seems to be the only way of ensuring that the daily stats are recorded for history purposes. I'd guess that if I didn't do the GE sync at the end of the day that day's stats would be lost the following day.
And today tapping the blue sync icon on GCM My Day results in the sync progress clock going to about the 3 o'clock or occasionally the 8 o'clock position then stopping. And the Step Details screen tells me to sync to see the latest stats. If only I could! I've down a hard power down (15 seconds button) of the V3 - no difference.
What I'm unclear about is how much of the information is direct from watch to GCM or how much is essentially via Garmin's servers. In which case what happens when out of mobile or WiFi coverage?
