I have become a blocked sender on my own Mail account

Resolved - it appears that with IOS26 it took my contact card and made me a blocked contact and it would not allow me to delete it in Settings. We had to open Contacts and delete my contact cards that had any common emails/phone numbers on. As soon as we did that I was no longer noted in Sent Mail as a blocked sender and no longer in the Settings - Blocked Contacts list. It took an hour + and they are escalating it but it will be reported to Engineers as a possible emerging problem in IOS26.

Hi thanks for the feedback. No I am not running any other anti-virus software. The issue is even when I unblock myself after I close Settings and reopen it and go to Blocked Senders - I am back on the list again and it includes my private and work mobiles and my work emails - basically my contact details are put into the blocked list as a sender. It doesn't seem to prevent me sending out or receiving replies but if I do a test from myself to myself it shoots it straight to the bin not even Junk. When open the Sent folder in Mail every single email has me as a blocked sender. I did have an email - from a known sender with an attachment that was a .png screenshot - this was opened on my phone albeit it seemed to take time to so - I don't know however if this issue existed before that.
