Multiple computers - iMacs, MacBook, Mac Pro - as of this week many functions in Canvas have stopped working. Clicking on item like Quizzes, Files, shows a blank screen. Different versions of Safari in multiple macOS versions from Catalina to Ventura. All became affected this week.
Please do not recommend Chrome as a fix. There are too many privacy issues. iPhones, iPads, and Macs are dominant in our environment, all use Safari only.
