It was selecting seats that was too broken to continue, though I mean, I already "worked around" the issue. I tried until it was less work to redo all the manual data entry in Chromium, I usually try pretty hard to avoid using it.

I don't doubt that it works for a bunch of people, others have stated things that don't work and had others say they do work, so something is up. Maybe we're using different versions or operating systems or installation dates with old configuration data.
