Fatal Exception: NSInternalInconsistencyException Cannot remove an observer <WKWebView 0x135137800> for the key path "configuration.enforcesChildRestrictions" from <STScreenTimeConfigurationObserver 0x13c6d7460>, most likely because the value for the key "configuration" has changed without an appropriate KVO notification being sent. Check the KVO-compliance of the STScreenTimeConfigurationObserver [class.]

I noticed that on iOS 26, WKWebView registers STScreenTimeConfigurationObserver, Is this an iOS 26 system issue? What should I do?

Our engineering teams need to investigate this issue, as resolution may involve changes to Apple's software. Please file a bug report, include a small Xcode project and some directions that can be used to reproduce the problem, and post the Feedback number here once you do. If you post the Feedback number here I'll check the status next time I do a sweep of forums posts where I've suggested bug reports.

Bug Reporting: How and Why? has tips on creating your bug report.
