I've been off for like I don't know three months and i know i had a lot of messages i never got to read from people i miss so do they like get deleted now or what? Just curious because a lot of shit has changed here apparently..
Perhaps try to click on the profile name of the person, than click on "message" and see if you either still see them or their is a button "see older messages" that you can click". Not certain, I don't have the problem... and first of all: welcome back Samantha! Really good to hear you again :-)
