When I embed the profile editor onto a webpage with the shortcode, it will only display properly on the device and browser that was used during subscription. On any other device, it shows “no subscriber found,” which makes sense since it doesn’t have the same cookie to reference. However, it is frustrating because I would like there to be a way to manage preferences from the webpage even if there is no user information stored.
that is intended behaviour. The profile page is reachable only if a valid cookie is set in the visitor ‘s browser or by clicking on a link inside a newsletter.
One further question: can the browser cookie be reset after every redirect to the profile page? This is because if two people subscribe on a shared computer/browser, it can override the form. Resetting the cookie would be a good way to ensure that clicking “manage subscription” in the newsletter footer fills the profile editor with the correct info based on whichever email address/client clicked it.
