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

Our best recommendation for this issue is to first test it with the latest 26.2 beta available, and if the problem persists, file a bug report on this right away.

You mentioned transparent buttons specifically, so in your bug report make sure you explain that if it looks like a cause for the issue.
