Hi,

I’m using Microsoft.Identity.Client, Version=1.1.3.-preview0012

And i’ve got this error on iOS. (android works fine)

@jennyf19 thank you so much you are really fast.

@Journeyman42 - That is not correct. We do not have broker for MSAL yet. I will update the wiki. It should be:

public override bool OpenUrl(UIApplication app, NSUrl url, NSDictionary options)
{
        if (!AuthenticationContinuationHelper.SetAuthenticationContinuationEventArgs(url))
        {
                return false;
        }
        return true;
}

Can you open an issue in MSAL with the logs and stack trace? this will help us investigate the issue you’re running into. thanks.
