I'm experiencing a critical regression on iOS 26 with a Notification Content Extension. extensionContext.open(uri) fails to open external URLs with LSApplicationWorkspaceErrorDomain Code=115 under specific conditions. Problem: When the main app is killed, and a rich push notification is received and expanded, tapping a button (specifically one with a transparent background, cornerRadius=0, clipsToBounds=false) fails to open its associated URL. Key Details: iOS 26 Only: Works perfectly on iOS 17, 18, etc. App Killed State Only: Works if the app is running (foreground/background). Works on Subsequent Notifications: The link will open if a second notification is received. LSApplicationQueriesSchemes: Confirmed to be correctly configured in the main app's Info.plist and present in the app bundle. Delay No Help: Adding a 1s delay before open(uri) does not fix it. My os_log statements confirm the button tap
