If I wanted to track a certain badge (for example, Enthusiast), how can I set that to all my profiles, on all my sites?
This does not work with the network profile update button.
Indeed. The badges to track are per site. And that is understandable since you can have earned that badge on one or more sites already. What badge should be tracked then?
I think it is fine this way, but if you feel like it, you can make it a feature request.
