For your own sake and the sake of anyone else who might be hitting this bug, I suggest you open applefeedback:// in Safari, file a bug, and post the FB number here or on the Apple Developer Forums.
Done, it's FB25286974 if anyone from Apple is reading.
Would you expect those on iOS 27.0[.0] to get the update?
I've reported it (I can verify the CRL check either failed or the CRL does not include the CA certs). No FB number was provided.
I also posted to security.apple.com, but they say they typically look at reports "within a week".
Report OE11044088569486, but currently it's just under review and invisible.
