When connecting Pivot Interactives to Canvas using LTI using the Safari browser, instructors or students may encounter a No LTI session error. This is caused by an incompatibility between the way Safari handles cookies and Canvas cookies.
In some cases, you may be able to resolve this:
In Safari go to Preferences
Click the Privacy tab
Make sure the Block all cookies is unchecked
Also, you may need to uncheck Prevent cross-site cookies:
Another solution is to use a different browser when using Canvas and Pivot Interactives.
