Make sure you clicked the 🏮 toolbar icon once on a Canvas course page and
granted permission for your school's domain. The item only shows inside courses, not on
the dashboard.
It says I can't see the roster.
Progress Report shows other students' progress, so Canvas has to know you as a teacher,
TA, or admin in that course. Students can't use it — by design.
Some columns are missing.
Canvas instances differ. When your school's Canvas doesn't provide a piece of data
(like last-activity), Progress Report hides that column and says so rather than showing
zeros that aren't true.
The report says it's incomplete.
That banner means a Canvas request failed partway (usually rate limiting on very
large courses). Hit Refresh; if it persists, use Copy diagnostic and send it
to us — it contains request timings and error codes, never student data.
