The "Expand/Collapse Group" button is not working for me once a quiz is saved (it works fine during quiz creation). Is this a a feature or a bug? If it is a bug, is there a mechanism to submit a bug report?
It's a bug that they are aware of. I even think I read somewhere (perhaps I was told) that this specific issue wasn't going to be fixed.
In general, Canvas isn't developing Quizzes anymore, putting their development effort into Quizzes.Next. They will fix functional issues with taking quizzes (like if you can't enter a decimal point in a numeric response), but things like this will most likely go unresolved.
To file a bug report, you click on the Help button in Canvas and choose "Report a problem."
