Safari 11.0.1 on MacOS 10.13.1. Issue also reproducible on iOS devices. When I visit https://mywindy.com/ I see the site issues an auth_token session cookie in the response to the first request. However, Safari does not submit that cookie in subsequent requests to https://mywindy.com/ leading to 401s. The issue manifests when "prevent cross-site tracking" is checked, and does not manifest when that option is unchecked. This would seem to be a simple first-party context situation. Regards, Jeremy
