Hi there, @ARD2 ...
Most often, you can report a problem with Canvas by accessing the "Help" menu within your school's Canvas environment. This Guide outlines some of the different options that may be available to you:
How do I get help with Canvas?
The one you would be looking for is "Report a Problem". You'd want to be on the page within your Canvas course where you are experiencing the issue and then use the "Report a Problem" link...as this will send some additional metadata along with your ticket/issue.
Also, here in the Canvas Community website, there is a "Known Issues" area where you can see things that Instructure (the folks who make Canvas) are aware of current issues:
Known Issues - Instructure Community
(I accessed this page by clicking on the "Explore" menu at the top of this page, and then I selected "Known Issues".)
I hope this info will be helpful to you in some way. Sing out if you have any questions about this...thanks!
