I recently updated my personal plan to the business plan but the google workspace is not updating to that plan. I received the following message: "Your domain is already connected to a Google Workspace account. Most likely, someone already registered this domain through Google or another reseller. Try another domain, or follow Google’s instructions to remove this domain from its existing Google Workspace account." I do not have another domain. I think I registered my domain through Google. I tried to follow the instructions but the DNS file is not recognized or found. Thoughts? I would like some of the functionality associate with the google business workspace. Any clue how I get those to link up? I am currently paying for nothing other wise.
