OK so I edit my heart rate zones under "settings" on Garmin Connect.
Then I attempt to send back to my device.
The problem is every time I try to send the new zones to my 310xt, Garmin Connect then tells me I need to log in my weight first.
So I do this.
Then I click on "Send to Device" again...
And...
VOILA! As per screen shot, it returns me to the same page, where it again asks me to "please provide your weight."
Bug in Connect?
Thanks for any advice.
