Chat doesn't work, then does, then doesn't

Seems to be random.
Log in and nothing goes into chat when i type into it.
sometimes i see things going into chat, but usually i don’t.
in the one instance where i did see activity in chat, my messages did not show up.

The same thing is happening to me. It seems like once every few days I can chat, but then I can’t again. Even same character could add a comment in chat, but next day could not. But everyday I can see the others chatting.

Playing offline, if that makes a difference. I heard they might make chat online-only in the future, but nothing about that in patch notes so far.
