When using `Editable boards for not registered users`, when I click on “Create Board”, I am getting an alert message saying “miro.com says Something went wrong” and in my console I get 2 errors
`DOMException: Failed to execute 'postMessage' on 'Window': Response object could not be cloned.`
`Uncaught (in promise) DOMException: Failed to execute 'postMessage' on 'Window': Response object could not be cloned.`
It works fine for users that have already registered with Miro. I have attached the necessary screenshots below.
