Garmin not synching with GC AND Strava

No, you are not the only one, but it has only happened a couple of times to me in the two years that I have had a 1040. One of those times was yesterday. When I finished my ride it didn't sync to GC. I tried again an hour later and it synced without a problem. I do sympathise with the folk who seem to have unending problems, but I have found the 1040 to be pretty reliable. Maybe I've just been lucky.

Syncing with Strava requires syncing with the Garmin servers first so it's not an additional issue, only a byproduct of the first problem. For me it only happens when the Garmin servers have problems and this solves itself after some time automatically.

But if you mention "reinstalling GC" then I gather you don't use the direct WiFi sync from the Edge to the Garmin servers but the bluetooth sync from the Edge to the Garmin connect app? This doesn't change much though, the app won't accept the activity as long as the servers are overloaded.

I don't need to reinstall (I had to recently, but that was a recognized bug in a new version of garmin connect) but syncing a ride is always a problem. I usually have to get into garmin connect and initiate a manual sync. If that doesn't work, reboot the garmin and the iphone. I come from the Edge 1000, so around 12 years of Garmin Edge and multiple versions of Android and IPhone and the problem has always been there, I can't believe it is such a big technical issue. I have an Omron blood pressure monitor and it instantly send the readings to my phone, never failed once.
