Mattermost iOS app 1.8.0 - SAML w/ADFS - Clicking login With SAML button displays white screen

Hey @paull, two quick questions:

  1. Are you using ADFS with IWA (Integrated Windows Authentication)?
  2. Can you help verify your SSL certificates are correct? You can use https://www.ssllabs.com/ssltest/ to verify them.
