Realm host's chat appears ###### after 1.2.7 update (Language : Korean)

Realm host's all messages(chat) appears ######### after 1.2.7 update on some devices. (For me, Language : Korean) It worked well on 1.2.6 but after the update, this problem happens and bothers me playing the game.

Language I use (on chat) : Korean
