Yep, it is working for me too. Incredible! And I've noticed you can add an Annual goal which is something I have wanted to see for awhile now as well.
Still need to be able to edit a goal though. And it looks as if the Today line that shows on the Dashboard is not being tabulated correctly. Mine very oddly seems to be a two days behind where it should be. It would also be nice if the Today line noted how many miles (or whatever your goal unit) you should be at.
So, not perfect... But thanks Garmin for finally adding the ability to Delete.
I must be overlooking it, but I can't see how to add an Annual Goal. Additionally, I read on the Garmin blog "With this new release, you can also create a goal with a past start date, as long as your goal end date remains in the future." except I am unable to pick an earlier date than today.
