That error generally indicates that Classwork’s web cookies aren’t working for the student. Typically that happens because Canvas and Schoology force us to launch Activities while surrounded by their interface. Since we’re embedded like that, the cookies we use are considered “third party cookies.”

Some browsers like Safari block third party cookies by default. In Chrome, they tend to be allowed, but it’s entirely possible your IT organization has decided to block them. It’s also possible that the student is launching in Incognito mode in Chrome, where third party cookies are blocked by default.

Chrome displays this icon on the far right of the URL bar when third party cookies are blocked:

If your student launched in an Incognito window, have them try without it. If the error still persists, try allowing cookies for app.classwork.com by following the steps in the next section.
