Starting on May 24, 2014, users who visit Canvas using any version of Internet Explorer older than IE9 (e.g. IE6, IE7, or IE8) will not be able to log in. Instead, they’ll see a message prompting them to use a newer browser.
Canvas has recently released an app that makes accessing Canvas even easier from the iPad. The app is free, download it from the App Store now. The file attached demonstrates how to log into Canvas using the app.
