Latest version of Express, couldn't upload last night. New activities this morning - but after rebooting/re-launching express and power cycling my Forerunner, nothing happens when I open Express. It just sits there, and I don't see how I can tell it to check my device for new activities.
Seriously, developers, please fix this terrible application. Just give us an option to get our .fit files so that we can do what we want with them. Stop being clever until you can make a reliable application that works.
