Encountered a weird bug last night with my friend. I cannot see their /say, /yell, or /e on their level 60 character while I am on a character 61 or above. The only thing I can think to have caused the problem is that they don’t have Dragonflight purchased. Their party chat and whispers both work just fine and I can see their emotes on my own lower level characters.
Same. I tested it out across many characters. I think its the fact that they don’t own dragonflight. Very lame, please revert
Looks like there’s a couple people having the problem 
I hope it gets fixed with the reset.
