Hmm... I've definitely found that I don't see any text (9/10) in the chat unless I'm actually signed in. Callan had messaged me about a similar problem - if signing in doesn't work reliably, try reloading the page, refreshing the chat window or using the pop-out chat option?
Let me know, Baztek. I saw you got on it but in the future...
