There's also the possibility that when signing into the app, it defaulted to canvas.instructure.com instead of the custom url your institution uses with Canvas. Make sure that your institution is included in the log-in information (yourinstitution.instructure.com).
Hi derriusrichardson! It's been about six weeks since we've heard from you. I wanted to take the time to revisit your question and make sure that you are able to successfully log-in to the Canvas app. I'm going to mark this question as "Assumed Answered" for now, but that won't prevent you or anyone else from commenting. Please let us know how things are going!
