The chat issue is frustrating issue and I know many of you highly rely on the chat feature to be fully functioning, plus it can help with the in-game experience.
This issue is a more complex than expected. Because of the complex nature of the issue, this is not a situation that can be promised a quick fix or a time table on when there may be a fix for the issue. What I can say is that our team is aware of the issue and working on a few things related to the issue to help alleviate some of the problems, though it may not fully go away until we have the resources available to fully address the chat issue.
