Unable to Block Calls on iPhone with new Tahoe O/S-Won't Retain Block Contact Setting

I am unable to block calls on my iPhone 14 Pro since downloading the Tahoe 26 O/S. I have the latest version 26.5.2 and it still does not work. I click on the number in Calls under Recent. Click on "i" or info button and scroll down to "Block Contact". I then click on Block Contact and then Side Button to Return to List but it does not retain the Block Contact. I've done it more than 6 times and will not retain the Block Contact and reverts back. Has anyone else been experiencing this problem?

I was also told by Apple that the limit was 20K a while back. I was at 17,000 so also figured I was good to go, but since 26.5 I was unable to block calls. I read something on a post about this same issue where a guy said that Apple lowered the number of contacts allowed to 3,000. Since I don't have faith in Apple fixing anything soon I figured maybe this guy knew what he was talking about. So I started deleting blocked contacts. With the number I had, plus they can only be deleted one at a time, this took me some time. Once I got below 3,000 I tried blocking a contact again and it worked! So, since in iOS 26 apple starting listing blocked contacts by phone number rather than chronologically as was done earlier, I decided to delete all of them to give me more room. This has been over a week and it still working as intended. Give it a try, YMMV

And just so you know, blocking numbers does absolutely nothing to stop scam or telemarketing calls. These people use different numbers for every call. Those calls will just keep coming.

Wondering which app is best for blocking spam calls

My iPhone has the latest version of O/S 26.5.2 . . .The blocking calls function has become disable and does not work.

I have only 3000 blocked calls/emails and the Apple Store said the limit is 20,000 --- so I am well within the limit of blocked calls & emails (It's all in one folder).

The new limit is 3000

Thank you! I wish Apple had informed all of us about this change. Even a trip to the Apple Store to meet with a technician couldn't figure it out. No one seems to know this . . . much appreciated!
