Just noticed something interesting/frustrating about the new portal: If you send text + a link (at the same time) in the chat, only the text gets logged to the ticket. The link does not get logged.
If you send text + an attachment (at the same time) in the chat, only the attachment gets logged on the ticket. The text is lost.
This appears to happen to both sides of the conversation. So if you are sending a URL or an attachment, send it by itself. Then send the explanatory/contextual text that goes with it. Otherwise, part of what you or the support person is saying will not be logged on the ticket.
Would love to hear if anyone else can reproduce this. I'll be attempting to verify next time i'm in the chat.
