I’m currently developing a spam number blocking app using CallKit. I’ve confirmed that up to iOS 26 beta 5, there is a bug where number blocking doesn’t work. In my current tests, the ringtone doesn’t sound and the blocking works fine, but the call still appears in the missed calls list, which is bothersome. If the bug is fixed in future versions (as it was in previous versions), is there a way to block the number so that it also does not appear in missed calls?

Hi I'm novice developer. I’m currently developing a phone number blocking app using a Call Directory Handler Extension. The blocking feature works perfectly on iOS 18.5, but it doesn’t seem to function properly on iOS 26 beta 4. The extension is invoked, and the numbers are passed correctly, but incoming calls are not being blocked as expected. Is there a known issue with CallKit or Call Directory Extensions on iOS 26 beta 4
