Error about gmail's integrated hangout chat service

I use gmail email, use the built-in chat hangout eM Client software, but when chatting, I just received the chat of the incoming message that can not see the previous message. If I use the software on some PCs, I can not see the messages I sent, only messages sent on the computer that sent the message, the messages I use on the hangout. Or other computer does not display. I think the eM Client can improve this for us in some upcoming updates, just add this as I think it’s near perfect, thank you. Best regards !

I agree with you! Same here. When I open emClient I cannot read messages that have been sent when I was offline. Any solution about that in the future?
