I've been using the Call Extension call blocking API since it was available in June without problem. However it is no longer working even with the offical 10.0.1 release.
To verify it it not my app that has a mistake in it I did this:
1) Create a new XCode project template app
2) Create a Call Directory Extension Target
3) In the extension template code that Xcode generates, change the 14085555555 number in the addBlockingPhoneNumbers method to one of my own number (yes I know they must be registered in order, this number is Seattle area code so its 1206nnnnnnn and hence is in the correct order).
4) Run the app, enable the extension, step through the extension code and confirm it is executing without problem
Make a call from the blocked number -> the number is NOT blocked.
Anybody else had this problem?
