“DJI drones were sanctioned under US Commerce Department and US Treasury Department regulations in 2020 and 2021. It is now illegal for any person within the United States to: Purchase any goods or services directly from SZ DJI Technology Co. Export certain data to DJI's servers in China.”
See: Apple’s secret deal to fund Chinese technology development and how US customs ensures nobody but Apple can import even genuine Apple parts and merch.
DJI themselves have publicly blamed "the compatibility strategy between the DJI App and Google Play Store", without elaborating. There's been no mention of US sanctions from DJI or Google.
