UPDATE 12/18/2025:
Through troubleshooting, we have found that clearing cache/cookies set to "All-Time" has been a proven solution:
Open Chrome, go to the three-dot menu > More Tools > Clear browsing data, set the Time range to All time, select "Cookies and other site data" & "Cached images and files," and click Clear data, then the restart Chrome browser.
We are currently aware of an issue where some students are having trouble loading Canvas on their school-issued Chromebooks. The problem is inconsistent and shows up in different ways, for example, a blank loading screen, getting redirected to the Canvas dashboard that times out, long loading times on certain assignments, or trouble signing in through SAML. From the reports and from our testing, these issues do not appear to happen on personal devices, only on student Chromebooks.
