Just purchased my 3-rd DJI drone (P4P+) from local hobby store, supposedly brand new. The box was open by store personnel (I was told), but the content didn't show any signs of use or abuse, sealed props included. The unit was up and ready to fly on first power up, with no warnings or issues whatsoever. It turned up that the drone is already activated. Indeed DAT files accessed by DJI Assistant 2 revealed several records made 10 days before purchase. Store management acknowledged my complain, but - since the product is functioning properly as far as I know - there's no reason to demand replacement or return. I was also clearly assured that the warranty is valid from the date of purchase, no matter who, when and why activated the drone on my behalf. One question remains a mystery, however: what is the activation procedure for, really?
