Research direction
Examine the Secure Shield view's update logic in the iOS client. Focus on the sequence when a synced tab is loaded: likely the shield icon briefly shows a default or incorrect state before the actual secure connection info arrives. Check if there is a race condition or missing observer. Look for relevant code in 'Client/Frontend/Browser/...' or 'Client/SecureShield/' and consider adding a guard to prevent premature display.
