So... This worked great. Solid, good UI, totally a 5-star app. Then I had the audacity to need it for courses at two schools at once. Instead of, say, keeping me logged in to both and letting me switch with a simple drop-down (like email apps and websites have for over 25 years) it instead logs me out of both after short periods of inactivity--say, the time it takes to read a section and take a short quiz on a publisher's app. 1-star for failing at basic credential management.

this app doesn't show grades. the desktop website version is a lot more helpful and informative. the layout is confusing. grades are not calculated correctly. maybe this is just an issue for the parent side of canvas, but monitoring my daughter's grades is a lot more difficult through the app and I don't receive the correct notifications for grade changes or assignments added

Used to work great. then it updated, and now my widgets never load. the notification are always blank til i refresh them, then they take a while and load. the to-do is the problem. It never shows ANYTHING. I'll have several assignments due this, and it says I'm "all done for now" and won't show me my assignments. The actual app itself also takes longer to load
