When your Workspot environment is configured using Azure AD as SAML Provider there is a possibility that an error page from Azure will be visible on Logout. Error page will show If the environment is configured with a Logout URL provided by Azure AD App.
In order to mitigate this issue Workspot recommends that the following Logout URL’s be utilized:
Logout URL with Tenant ID - https://login.microsoftonline.com/{tenantId}/wsfederation?wa=wsignout1.0
Logout URL without Tenant ID - https://login.microsoftonline.com/common/wsfederation?wa=wsignout1.0
