It's hard to finish RAID BOSS when the Chat does not function! It happens to me in all browsers. Am I in KanoJail?
If you were banned from WC you would have gotten a notice, also not sure kano is in today, but ya need to mention which platrofm ya on, FB"" server2 ? Kong etc
I'll make sure it is working properly, but you might want to submit a Support ticket as well. They will be working over the Holidays.
