Hi schlingo, thank you for the response! I'm using 5.1 which seems to be the version where this was added. I've already seen the article, I'm just a bit confused why I see it only in one chat and not the others. Do you happen to know why?
I noticed a "Messages in this chat are now protected by Perfect Forward Secrecy" message in one of my chats. I didn't do any change myself and no other chat is showing this message. What does that mean? Why am I seeing this message?
