Can anyone at DJI tell me how to reply to DJI support tickets?

I have a support ticket open and have been contacted through it by DJI, but I am unable to reply. I type in my reply, but there is no "send" button, and if I just press enter on keyboard nothing happens!  

Help please!!

Hi,would you paste the screenshot?
