On a number of occasions I have not seen all the messages by individuals in a thread, per the conversations app. The only way to fix is F5 (reload). And the problem is - you realize it after the fact - after someone says I am blind (since I am saying something or adding resources; and it looks like I didn't ready the previous message or messages). It has happened twice now.
E.g. I see 10 messages; I post a reply; someone says I am not following; I do a refresh and lo and behold there are for example 3 messages above me that didn't appear when I entered the conversation thread.
