I have an iphone 16pro and the latest iOS version brought the new feature of screening unknown numbers, where it asks the caller why they are calling. However I hadn't been getting any calls for a while to the number. Someone then said they had tried calling me and it just rang a few times and hung up. I tested calling it and it didn't ring at all or show the incoming call at all. I had it set to 'Ask reason for calling' but have now disabled it and it now seem to be working again.  I know it worked intially, but it seems to have stopped, possibily after an ios update. Anyone else had issues with this new feature?
