The outbound journey allows you to stop the journey in the middle if a contact doesn't open the mail or if he doesn't submit a form.

So if the IF condition in on "false", his journey ends.

In the new real time journey, his journey doesn't end, but it continues until the end. That's not the way it should be, is unusable for us.

I opened a ticket and they told me to develop a "custom trigger" with the exit behaviour.

But it doesn't make sense, all software around allow that, and customer need to use a user friendly tool.

So at least, add a OOB trigger to exit the journey if the condition is not met.
