I am a student and my menu icons not showing, buttons on left side of canvas are missing, they show as blank and won't let me click on them. The account icon is not showing, the courses icon is not showing, the history icon not showing, and dashboard contents not showing. The icons that do show like the inbox icon does not allow me to use the feature. My classes are current and active, Ive deleted cache data, I am on updated Microsoft browse, and I have tried to sign in and out.
