I have a data platform set up in HUB with a custom domain: santafedata.org. The domain works well, but when you Google "Santa Fe Data Platform" the search result is still the old "hub.arcgis.com" domain. When you click on it, it takes you to the page with the old domain. If you navigate within the page, it remains the old domain. The only exception is when you navigate "home" within the page, it will revert to "santafedata.org." How do I ensure all search results and page navigation is consistently using "santafedata.org"?
Are you still experiencing this issue? I now see santafedata.org as one of the top Google search results when executing that query. I believe that it's common to experience at least a several day delay before search engines pick up the changes.
