I got for the 3rd person in a few months the mssg "you can't reply to this conversation" -to a person that I literally spend 24/7 with and know they haven't blocked me, and I can send them message on pc, only issue is through messenger. No updates showing, clear all cache, plenty of space, still only allowed to send screenshots (other share options probably work, def not gifs). I mean, it's messenger,you're supposed to be on top of the world, we sell our souls to you, at least make it worth it.
