Terrible updates

Over Two and a half months ago you made an update to messanger which is very inconvenient. Now, one cannot keep there conversation areas clean, up to date, uncluttered. You cannot erase or delete any of the conversations or messages that you dont want, or are outdated and not appropriate. Not being able to do what you want is not user-friendly. It no longer is fun or functional, nor is it a joy to use.
Its a big mess!!!

PLEASE, PLease PLEAse fix this ASAP-
