Blueprint not detecting changes to sync

[dtod]

I've tried this in two different blueprints and multiple browsers, but nothing I do seems to trigger the blueprint functionality to prompt a sync. I've asked support and they've not yet been able to help.

Is there some trick to it?

I'm the primary account admin. The BP is validly associated to over 800 courses (via the API), and I've added content after associating to those courses. I've tried this with an existing course and a brand new, from scratch, course.

I would add that in another blueprint that I set up a while ago and is associated to just a couple of courses, the functionality works just fine.
