How do I permanently block numbers after iOS 26.4 update?

Having issues blocking numbers with the new ISO 26.4 update. Was fine before the new update but now if you try to block them, they just unblock themselves.

Mine are still able to be successfully blocked as well. Verify the number that you are receiving is one you have blocked before. What is typical is that companies will use spoofed numbers and even though the company name will appear as the same, the number is constantly changing and blocking those are useless. The only real use of blocking numbers is for a known contact or from a number that has called you more than once. For a number that has called you more than once, it will be noted in your Call History with (x), showing how many times they have called.
