Message App - IOS 26 no longer filters unknown text senders.

After IOS26 update, my iPhone message app no longer filters "Unknown Senders". This setting has actually gone and seems to be replaced with "Screen Unknown Senders". However, the new option it does not do the same as old "filter unknown senders". Also message grouping in display no longer allows view of "Known Senders". You have to see the clutter of ALL messages or just unknown.

Interrupts are driving me bonkers. Can this be fixed? Apple watch also is doing same giving me alerts on "unknown senders". I have tried rebooting both devices.
