Hello,
  I talked with customer support and they told me I need to enter the priority shipping code they give me after I order, but I finished ordering and there's no place where I can add it and the chat also closed.

So now I'm without a code and don't know if I can use it anymore as I already ordered? Could anybody help me with a code and an explanation on how the hell I should use it?

Thanks in advance

I have not found a place for the priority code either on the order page. I sent an email to store@dji.com with my order number and the code. Earlier this years this seemed to work when I ordered Mavic Air. Hope it works this time too.

Hi, thanks for reaching DJI Forum. We do apologize for having issues. Kindly refer to the sample photo below. Thanks.
