The delay problem above is solved here
Also, one more question and I’m sorry to mention you @rctatman, is there any downside by running Rasa Core this way compared to using rasa run method and connect to rasa by using API instead? Other than the need to setting the server by myself, the only thing that I can think of is probably activating reminder events which I’m not sure how it will work if I run it without rasa run command.
