Block numbers not in time order?

Hello symphonie33,

Thanks for asking the Apple Support Communities about a blocked contact.

I was able to block a contact, and it did show up as the very last number in the list. If it was the last number you inadvertently blocked, it's possible it's at the very bottom of the list in Settings > Phone > Blocked Contacts.

Thankfully blocked contacts can still leave messages, you just aren't interrupted with ringing or Notifications. Block phone numbers, contacts, and emails on your iPhone, iPad, or iPod touch - Apple Support

Thanks and have a wonderful day.
