Have a faculty member who has clicked Allow Liking for an Announcement - that's it, no allow graders, no sorting.

But, no like icon appears for the students.  We've verified that it works for discussions, but does not for Announcements.

What are we missing?  A setting in the course, in global settings for the system admin?

Can't seem to find any reference to liking in announcements in the literature/guides/discussions...

Thanks!
