That said, I'm using a 910XT and a 610, neither of which support the VO2max features that the 620/220 have. Previously I used to be able to enter VO2max data on the settings page and this would be used to render the VO2max widget on the classic dashboard.
I noticed that you could pick a report and added this back, it wasn't intuitive. But I don't have the add to dashboard button anywhere on the menu items, I'd like to put a few different reports out there on the dashboard, not just one at a time.
