Hi, We have a custom .net web app which single signs on users to Canvas app through microsoft 0365 user account. If a user logs out from from the custom app, user is logged out from Microsoft platform but Canvas app is still active and it only logsout if the page is refreshed. Oauth is the communication protocol. Is there anyway in Canvas app to restrict user performing any operations after its logged out without refreshing the page? How can we check logged in user access token is still active?
