Navigation between dashboard and landing page

I'm working on a printing and drop-shipping website which has been growing fast lately with users and features so it becomes difficult to manage IA. Here is the situation.

It has a landing page, which contains some of the core features (product list and mockup generator). If you register and sign in, you land in a dashboard, which shows all your stats and gives you access to your personal stores, integrations, reports etc. But if you still want to access home page, you have a link on the upper left corner to swtich, and vice versa.

This feels a bit confusing, but rethinking the whole information architecture is not an option right now. Here is the navigation example:

I wanted to know if anyone has been dealing with similar navigation funnel and could share some experience or best practice advice.
