I just got a brand new Forerunner 645 and I was so excited because the watch can replace both my aging FR 620 and my Fitbit Charge 2, which I was using for all my sleep and activity tracking. I've had it for one day but not all data seems to be uploading to the Garmin Connect app on my iPhone or even when I connect it to my computer. The watch is indicating that it is logging all the data - my HR data shows up there. It is NOT showing up on the app or on the Connect dashboard. My run this AM only showed up after I connected to my computer. I was using the HRM-RUN so that HR data uploaded, but the data for the rest of the day with oHR from the watch isn't there. I can't figure out what's going on. Anybody else having this problem?
I had the same problem when I got mine too. I think i was told to remove the watch from the app on your phone and then reload it. worked like a charm!!
