I've recently changed the endpoint for server to server notifications for 'Sign in with Apple'. Since doing so I'm not getting any notifications It's not an issue with my server as I'm still getting IAP server to server notifications from Apple. When changing the endpoint I got the popup: 'Adding or removing any capabilities will invalidate any provisioning profiles that include this App ID and they must be regenerated for future use.' - Could this be the issue somehow? I let xcode manage all my signing and provisioning profiles so I wouldn't have thought so? The app is still in beta so there's a version on testflight, however I'm trying this with a version installed straight from xcode to my phone. Has anyone else done somehing similar, am I missing something here? The actual sign in with apple works fine, just not the notifications when they change their settings.
