And make sure you're actually signed into the same account on Garmin Connect (web), Garmin Connect Mobile, and Garmin Express. All are simply different ways of connecting to the same database of activity and fitness data. When you sync via wifi, you're syncing with that database directly. When you're syncing with bluetooth, you're syncing with that database through the mobile app. So if you're actually syncing through bluetooth or wifi, you should see the same data in the web portal as well, without needing to also connect via Garmin Express.
So logged out of phone and back in with same account, tries to sync like new again and all the phone data that hadn't been sync'd online has now gone. WTF!!!
Before you logged off on the phone, did GCM have error messages about no Internet connection? As far as I know, that's the only circumstance in which there would be "phone data that hadn't been sync'd." In airplane mode with bluetooth turned on GCM can still see the watch and pull in step data etc. to the phone, but at the same time there are red banners and gray exclamation points that let you know that there is no Internet connection. The moment there is an Internet connection, all of that data in GCM is sync'd back up to the Garmin Connect platform.
Is it possible you have two different Garmin Connect accounts? In that case you might have been logged into one, and all of that older data was synced up to Garmin Connect. Then you logged out and logged back into a different account and that one has no data? Otherwise you should call Garmin Support if there's actually an issue with your data disappearing on Garmin Connect.
I thought I might have used a different account on the phone but it was the same. If you sign out it sets up like new. Any data that hasn't been updated is lost - along with app settings on the phone. That's what I found, tried it a couple of times. its not like a normal logoff, logon process for other apps!
I had several activities on the watch that wouldn't sync - until I got home, connected the cable and they uploaded via Garmin Express. Before I tried that I tried the watch sync via internet connection (at home) too. Only the cable sync seemed to finally upload it.
Thankfully I hadn't lost those. Though they were in Strava which is really where it counted. :-) After uploading they then downloaded to phone app too. So just really lost steps, sleep and non activity data for a few days.
Sucks but better to have done that now than a month or so down the road. That would have made me very miffed!! :-)
Mick,
