Thanks, Eskimo. From my side, I no longer see these crashes in 14.3, only 14.2 and below.

Hi Eskimo, any luck or updates regarding this issue? I've also filed FB8970895 to track this.

Putting the message that we only see in Crashlytics aside, the Xcode Organizer crash reports (attached in a previous message and in the FB) closely matches what we see in Crashlytics. Is there anything we could infer from them?

After re-reading some of the forum threads and TN, am I understanding correctly that content filters are only available on iOS 15 and above for apps that use Family Controls to request authorization for .child, not .indvidual? Trying to save a content filter configuration after requesting individual authorization throws a permission denied error in a TestFlight build. https://developer.apple.com/documentation/technotes/tn3134-network-extension-provider-deployment also mentions that it is available on "per-app on managed devices". Is this completed unrelated to Family Controls?
