No blue submit button

Community Novice

Help, none of the assignments posted by my teacher are showing a blue submit button, so I can't upload my work. I spoke with the teacher, and when she goes to student view, the button is there. She also checked my profile, and it shows I'm enrolled in the class. We tried zooming in and out to see if the button would appear, and nothing. What should I do? I've tried this on a couple of computers.
