I have been very happy with my Forerunner 310XT, which I have used every day since buying it four months ago. I upload each day's workout to Strava, MapMyRun and Endomondo. This has been working perfectly--until last week. After 5/27/14, the three sites don't see any workouts after that date. The data is getting transferred to Garmin Connect using ANT+, but the three sites are not seeing any new data. I have updated the GC add-ons to 4.2.0. I suspect that Garmin may have changed some security protocol, and that broke the connection.
Does anyone else have this problem? Any suggestions? I can export a GPX file and import into the sites, but that's a pain.
Thanks,
Joe Parsons
