I'm trying to display one of my bookmark lists on a map. I am properly authenticated (as far as I can tell; other features work perfectly well) and I do have bookmark lists. But the dropdown field remains empty.
I checked on various days, the result stays the same: I select my username, click on "Get Lists" and get back an empty set (one empty field in the dropdown). However no error message.
How can I further troubleshoot this?
