ADO integrations are sending to legacy domain "https://fredwin.visualstudio.com" instead of sending to "https://dev.azure.com/fredwin". Though the integration works as expected, clicking the link to the integrated record sends to the incorrect domain, where the functionality doesn't work as expected.
Update the integration to point to the new domain.
As noted, the integration functions using the deprecated domain, but when a user follows a link that uses *.visualstudio.com the site has limited functionality and errors, leading to confusion and poor user experience. Since this domain is legacy, please update to the new format asap.
