How do I know what version of Phantom 4 Pro I have?  Does it say somewhere?

Hi there. Thank you for reaching out. The best way for you to identify what specific model of drone are you using is by checking the serial number. Get the serial number and visit this link https://service.dji.com/active/search to check the model with the activation date. Should you have other inquiries, please don't hesitate to reach us. Thank you.

Ok it shows me that I have a Phantom 4 Pro I knew this already.  And it shows I activated it on 3/31/2018.  How do I know if I have a version 1 or version 2?
