If you have access to different products within your Wizeline account, you can easily switch between them in the products drop-down. The products drop-down in the left navigation menu, above "Home", will indicate which product you are currently viewing.
Clicking on the arrow next to the current product name will open the products drop-down. From here, you will see all the products you have access to and you can click on switch your view.
Note that multiple products are only available to paid Wizeline users -- free Starter plan users will not be able to manage or view multiple products.
