When users attempt to log in to our mobile app using single sign-on (SSO), they may encounter a blank screen. This issue typically occurs in environments using Active Directory Federation Services (AD FS) for SSO, where Windows Integrated Authentication (WIA) is not correctly configured for mobile user agents. When the mobile app's internal browser attempts to negotiate authentication, ADFS fails to provide the correct interface, resulting in a blank page.

To resolve this, an AD FS Administrator must update the AD FS properties to support the user agents used by mobile devices. You must add the mobile-specific user agents to the AD FS configuration to allow successful authentication via the mobile app.
