Just so I'm not making an empty comment, here are a few quick complaints:
- Confusing differences between calendar vs module views that differ from class to class depending on where the professor tries to put things
- Zoom is shunned to its own tab rather than integrated with the calendar, causing students to constantly ask each other for the password for every session
- Everything (tests, midterms, homework assignments) is called a quiz, and it's often unclear what is going to be graded or what allows multiple submissions until it's too late
- Notification settings are terrible and most people stick with the settings they set in the first week, meaning some of my classmates are just now realizing they've been missing announcements or grade postings
- If I get an email that a teacher has released grades, I have to go to Canvas to open it - and sometimes it's not even true
- Notification counts are ignored because they appear even on things I've already seen but just not clicked on from the "home" view
- Replies to my own discussion posts are mixed in with replies to everyone else's posts, meaning no real discussion is had
