I’m facing the same issue when trying to add Website URLs for Sign in with Apple under a Service ID. Each time I try to save, I receive the following error in the network logs: Request URL: https://developer.apple.com/services-account/v1/bundleIds/********* Request Method: PATCH Status Code: 501 Not Implemented Referrer Policy: strict-origin-when-cross-origin And on screen: Unsupported Request PATCH to http://developer.apple.com/services-account/v1/bundleIds/********* not supported. Reference #8.e0e1502.1756116573.39d998e It looks like the portal is rejecting the PATCH request when saving Website URLs. Has anyone else experienced this issue, or is there a workaround to successfully save the configuration?
