Hello there, firstname.lastname@example.org Welcome to the Canvas Community. Thanks for posting your question. By chance, are you using either Edge or Internet Explorer as your web browser of choice? If so, please try downloading either Google Chrome or Mozilla Firefox to your computer. Both Chrome and Firefox provide a better browsing experience when navigating around the Canvas environment. This is also true when it comes time to submit assignments/homework to your instructor. Please try one of those two browsers, and then come back to this posting to provide an update letting us know if this helped to resolve your issue. Thanks!
