I know that there are two plans for workers and page combined. bundled and unbundled. But I cant explain how it is working. Can someone from cloudflare team help explain this ? And what is the best plan for my use case ? I mostly use cloudflare pages for my organization. Its fine for static export but issue occured when I deployed next-on-pages. I want currently using Unbound but I am not sure if this is right plan for me ?
