I have the same problem with garmin connect. Null activity, one file transfer failure, but also missing fitness icon in calendar! (picture: blue icons are fitness activities, grey icon is a null activity) Why does Garmin not solve this problem? It has been a few weeks, it can not be so difficult for them to fix it.
I've tried many times including reset to factory default, uninstall app, and uninstall programme on my Macbook and install back all related apps and software once again. Still failed.
I downloaded via Wifi but I get the "1 File Failed" when completed transfer. Of course, I also use the USB cable to up/download it. And I also use a Window PC but also failed to transfer the calendar data. Nothing shown up on my Fenix 3 calendar no matter how i try to press the "transfer to devise" button many times. This major feature that doesn't work on this package is a joke! This is the first time I use Garmin's product and it's also a top end product among their GPS watch range. I've never had an single issue for my Polar CS 600 up/download plans and datas since 2009. Customers having this issue for a few months and Garmin still could not take care of it makes me feel I've been being ripped off for paying US$550 and without the said feature in the advertisement. Really Really disappointed!
