did you have to enter your serial number at any point? I've never seen that step. I'm wondering if you have to click through the verification link in the email from Skypixel.com, but it appears their site is down because I keep getting 403 errors. So frustrating!I can't remember. I think once your logged into you DJI account in the app it creates your profile and activates. I did it with the Inspire app because I received my P3 last Wednesday and that's all that was available then.
