I just purchased a forerunner 405 and I am very disappointed. The watch works fine, but the synchronisation with garmin connect is dreadful. As I browsed through the forum I saw, this was a problem already a year ago! And still not solved? Real disgrace!

Th sync from watch to Garmin Connect is sporadic at best. The first few runs synced fine. Than nothing. Than I forced a sync from the watch, and only the last run synced, the older ones are probably stuck in the twilight zone of the Express folders.
The sync from Garmin connect (goals, tracks, trainings) never worked.
It was a no-brainer for me to go Garmin when I was looking for a GPS watch, but after this I have to say my next purchase won't be garmin unless there is a big surprise in the next few days!
Is there any plans to make Forerunner 405 work with Garmin Express? Any solution emerged since 2014? Any tip? Anything?
