There is an issue with Securly blocking clean/approved sites, such as Canvas. We made a change on our end, which will resolve the issue until Securly implements a permanent fix. This change should be automatically pushed to District devices, however, if you or your students continue experiencing issues, please clear cache and cookies, then reboot the District device. We apologize for any inconvenience this may have caused. Please visit status.securly.com for further details and status updates related to this issue.
