Salesforce Field Service App — SSO Login Error: "Frame Load Interrupted"

Issue Description: 

Users attempting to log in to the Salesforce Field Service app via SSO encounter the following error:
"Server Error - Can't connect to the server: Frame Load Interrupted".

The login process fails without completing authentication.

Root Cause:

-> This error occurs when the SSO authentication flow is interrupted inside the app's internal WebView (WKWebView).
-> This is commonly triggered by:• An MDM solution (e.g., Azure/Intune, Jamf) with an Enterprise SSO extension enabled•
-> The SSO redirect being blocked within the app's internal browser• Advanced Authentication configurations (e.g., Azure AD) that are incompatible with WebView-based login
