What should I do?
Hi jamie trujillo and welcome to the Canvas Community! There can be a number of reasons that you cannot see your course(s) in Canvas, so to find the best solution you may need to contact Canvas Support or IT at your institution so that they can investigate your situation. For example, sometimes the formal registration process places students in classes and this may not have been completed in your situation. This question was posted in the Canvas Community which is composed of Canvas users from a number of different institutions. While we can answer a number of questions, we cannot look at your account to problem-solve something like this.
I have run into this situation a couple of times with students at my institution. You might check that you have the class set as a favorite (see How do I customize my Courses list as a student?). This fixed the problem a number of times. You can also do this if you are using a mobile device (see How do I view Courses and Groups in the Student app on my iOS device? or How do I view Courses and Groups in the Student app on my Android device?).
I hope this issue gets resolved soon and best wishes!
