@robert-vanderli , I'm sorry to hear that you're having problems with Canvas. Does this problem seem to occur on different computers? Have you tried switching Internet browsers (Firefox or Chrome)? I'd start with this first. Also, have you talked to your Instructor about the problems you're having? If not, then I'd definitely let them know. In addition, if you haven't already, please contact Canvas Support (Help link --> Report a Problem). Getting support involved is important because they can do a lot of back-end trouble-shooting that your Instructor and the Community (where you posted this question) can't do.
Hope this helps!
Hi @robert-vanderli ~ I hope that since you initially posted your question that you've had more reliable experiences with Canvas. If that is the case, what helped improve your navigation? Since it's been a while since we've heard from you, I'm going to mark this question as "assumed answered" but that will not prevent you or anyone else from commenting. Hopefully, we'll hear from you soon!
