Publishing agent workflow after twilio connect

I have connected my agent workflow to an existing twilio phone number. That worked very well and after that connection I published my workflow so I have a production environment which is connected to twilio number. I also checked the integration settings which shows me that my twilio number is connected with production environment.

My problem is when I call the number the agent has the same problems like an older testversion which I already fixed and published. Is there any delay where I have to wait for? What should I also have to take care of?
