If you work with multiple Blitzz domains there is good news. You do not need to log in and out of the different domains when you are supporting different sites. Simply go to Blitzz Admin Settings and look under General Settings and select Switch Domain.
After clicking on Switch Domain a listing of all the domains you have access to will be displayed.
Select the domain you want to access and then you will go to it bypassing the login screens. The requirement is that you are setup as a user with the same user ID (email address in most cases) in each domain.
