After the new update, no welcome screen was the only way to use chat with maximizing triggers.
When chat window maximizes, the welcome screen does not go to conversation view, showing the trigger it stays as it is. Now it’s completely unusable as visitors doesn’t see message (trigger content) 
, just welcome screen.
Please bring back the old separated version so that you can turn off welcome screen all together or fix widget going to the conversation view after the trigger, not just when the visitor clicks on the bubble.
