Seriously would it be that hard?!
Every now and again technology just will have a little spat then get over it. Like the GWS outage today for example. So when something like that happens at the same time my Fenix syncs to my phone (successful) then my phone tries to sync to Strava (failed), I end up with Garmin device & app thinking everything sync'd just fine but it never made it through. The only option is to export to a file then manually upload that- why oh why oh why can't they just stick in an option for manual sync?! On the phone app as well as Connect website. First world problems and all that I know...
