ASWebAuthenticationSession, watchOS, and Cookies

I have an app that uses the Slack API, and I’m trying to use ASWebAuthenticationSession on watchOS 6.2 to allow for login on watchOS. I was able to display the login form and enter my username and password, then I saw this displayed:



Unable to set cookie

You need to enable cookies to sign in.


Is this something Slack needs to account for, or is there a way for my ASWebAuthenticationSession on watchOS to enable cookies?
