I've had a FR620 registered to my Garmin Connect account for a couple of years now and I recently parchased a FR630 and I am just wondering if you can have both watches registered to the same GC Account. I've had some issues lately with the 620 (freezing mid run or wild paces in areas where it would work fine before) but I also read in the forums that the 630 doesnt have yet the alerts when creating pace ranges in custom workouts so for this reason I was thinking of alternating between the two watches until the latter is sorted out.
I guess the question is if anyone has done this before and if they have encountered any issues of having and using two devices on the same GC Account. I want to know before I use the 630 and to potentially avoid deleting any of my previous activities and information on GC.
