I'll type out a message, and then when I hit send it will show a loading sign and then not send. The message just dissapears. It always happens if I haven't refreshed the page recently. I typically expect this to happen, so I normally will copy the message before I send it. And then I send it and the message just dissapears. So a lot of the times I have to retype the whole entire message again and this extremely frustrating and time consuming when I'm working.
