I have Google Docs and Twitter. I follow the steps and enter the same death loop: “Oops. It appears you have not set up your Twitter” (which I just did, again and again.)
Glad you are up and running. If you prefer to do this from a particular account if you run the setup in an incognito window it should work. You should only need to do the initial setup once in incognito mode. Once setup multiple accounts is not an issue 🙂
