The ability to have a single place for our customers to go to for help and the chat integration allows us to connect immediately with our customers! The only downside that I can see is that it's not always clear when the answer has been received by the person who needs help.
Sometimes we get emails asking if we've gotten a response, but there doesn't seem to be any way of knowing this. Also, sometimes we don't know how long it takes for the chat agent to respond. We're able to communicate with our customers right away, and they can just click a button or tap a keyboard to ask questions.
