Chat window not updating

After latest (March 24) patch, chat window is not reliably updating… it gets stuck after Guild Notice typically. It MAY update once randomly when in a zone, and its a whole bunch of back logged chat inputs, but then it gets paralyzed again.
At this point, the chat window is useless, as I cannot interract reliably with other persons and see their responses. I have however verified that my outgoing chat, even if I do not see it in my own chat window, does in fact go out fine.
