QR Code

Hello team, Are you able to help me? I have been trying to use your website for mini simulations. I connect my phone to a laptop via the QR code to have my phone as the controller and the laptop as the display. The issue is that I have to keep pressing enter to change the observations on the display monitor. Sometimes observations will change but not all of them. Are the observations meant to change one by one, is there something I am meant to be doing? Any help would be appreciated.
