Looks like the problem is still there and not fixed in iOS 18 public version.

It's a problem because people add known spammers to their contacts so as to identify them and not pick up the call. So with this regression, all the known spammers that were added into users' contacts will be able to call users again.

@DTS Engineer this is issue is still persisting in the production iOS 18 and 18.1 versions as well the latest beta builds. Is anyone looking into this please?

@Papaductions is the blocking working for your app when the number being blocked is in the user's contacts? Or is the call being let through if the blocked number is in the phone's contacts (incorrect behavior since the number should be blocked)?
