That's what I often get prompted with once I'm into my half-dozenth comment. But when I click the link, I'm told the attempt to move it failed. So I carry on writing comments.
How does one 'move a discussion to chat' ? Should I expect this link to do it automagically? Do I need to roll up my sleeves and find how chat works, and copy paste or do something else manually?
I'm logged in and have 80k rep. I have an up to date browser, but it is Chromium (74.0.3729.169), running on Linux Mint 18, would these have anything to do with it?
