I just stumbled over something I did not notice building my app. Apparently using headers from next/headers is opting my entire app (SSG) into dynamic rendering. I used it to build breadcrumbs. Ok not problem I find another solution for this. But now I am concerned that draftMode does the same thing. I basically fetch all pages from contentful and use draftMode to see a preview of my page if content isnt published! Can someone explain what is the case here?
