NEFilterDataProvider development-signed bypass no longer working on iOS 26.4.2 — regression or intentional?

Hi,

Has the get-task-allow development bypass for NEFilterDataProvider been intentionally removed or changed in iOS 26?

Previous DTS guidance in thread/31109 confirmed this bypass existed. I note that WWDC 2025 Session 234 states "iOS system-wide content filter is supported on supervised devices only" without mentioning it.

My production deployment is supervised MDM devices — I am purely asking about the development testing path, which is not working for me on iOS 26.4.2. All I get is NEConfigurationErrorDomain Code=10 "permission denied" before my app code even runs.

Thank you!
