Conversations in the list pane, and their contents, don't update automatically after resuming the computer from sleep, if there's been any activity from other devices.
Like, when I chat from my phone, while my Mac is sleeping, and then I wake my Mac up and go to the app, the conversations in the list are still the same (they should be re-ordered according to the latest activity) and the contents are still the same.
Not sure if it takes a little while longer to happen, but I waited for a minute and nothing changed, I had to reload the app.
