Hi @Chris_Hofer ,
Thank you for your reply! My coding looks like the copied code below. I don't have the class as "enhanceable_content accordion" or use href="#". I have used those to create tabs before, but because they didn't render in an ipad, I switched to the dropdown accordion menus. When I checked with students yesterday, two subjects can see Canvas without issue and the other two cannot. I will look at the link you posted and see if it will help! Thanks again for reaching out.
