Angular.common.http, ASP.NET Cookie Based Auth and CORS

Hi all -

I’ve been banging my head against a wall trying to get an Ionic app talk to an ASP.NET server with cookie based authentication. In short, the authentication cookie is not being sent after the authenticate request completes successfully - I’ve verified this with wireShark. WithCredentials is set to true, so I would expect that the cookies would be returned appropriately.

(this is using @angular/common/http, running on an Android device)

Has anyone else run into this?
