Feedback from a few people has been that it would be nice to have the navigation to the Exchange be nested under Resources on our main site. The navigation to the top right corner does not feel intuitive.
There are a few ways that you can navigate from the Exchange back to the main site. From any of the pages on our website, including the Exchange, you can always click on the Inductive Automation logo in the top left corner to be taken back to the Inductive Automation home page. Another navigation can be found when you are inside of an Ignition Exchange resource card. When inside a resource card you can click the home selection at the top left of the resource card - this will navigate you back to the IA main site page. You also can select your account icon in the top right corner, select 'My Account' and navigate to the IA hope page as well as other sites such as Inductive University, the Community Forum and other useful sites.
Also I think navigation from exchange back to IA main site does not exist.
