I don't know if anyone else is having this issue. I have the DJI Assistant 2 for Mavic on both my pc and laptop and when I plug the smart controller into either one I get this message, "current charging speed is slow. Please use the charger that comes with the device for a faster charging speed. I have uninstalled and reinstalled the app several times on my computers and still get this message. When I first used the Smart Controller I never had this issue, but it accrued after one of the updates of the controller and I don't know which update. I've had this controller for 3 years now and love it but this is frustrating that it won't update with one of my computers and have to update over the wifi on the controller.
