Has Unknown Senders Bug in Messages finally been fixed

[GC251114]

Many versions ago , the setting to have messages sent from numbers not in your contacts , go into the Unknown senders Folder actually worked. This was a great addition as kept unknown senders super ate from other messages. Then .1 versions arrived & this feature was broken. Not only broken , but never recognised & fixed by Apple. A message came through , number added to home screen , yet no tone. This is how it was meant to work. Open messages & the message wasn't in your list of messages. Again how was meant to work. Then once you'd selected & read the message , the message was added to your list of messages that were contacts. Then any subsequent message that came through via that thread , it no longer appeared in Unknown senders. This was different to how it originally worked on release where it stayed in the right folder. This is a crude bug , & lazy of Apple to not even recognise. Is this fixed in this first beta ?
