Hey, this is part of the learning process, right?
So looking all around the Canvas ‘help’ community, there’s a tab for “resources.”
All of the resources are on this site. None of them go to the mysterious “resources” place.
However, there are things that you’re asked to use that do. You’re not told that they are in a special ‘instance’ of Canvas (the ‘resources.instructure.com’ instance).
Design hint: Don’t give the same name to things that don’t require the same behavior.
(But what do I know?)
Hey, at least I know, now, to look for that kind of thing — and to assume that Canvas will not have good design.
