I recently purchased a DJI smart controller for use with my Mavic2 pro. Did a test flight and all works well. My problem is getting the GoShare function to work. I'm using a iPhone 6s plus with the latest iOS but whenever I try to scan the QR code on the controller all I get is 'Cannot join Controller ****' I've tried with the home Wi-Fi and the personal hotspot on the iPhone, neither work. I do note that when I tap the go share icon on the controller the Wi-Fi fan turns from blue to white suggesting that it is disconnecting from Wi-Fi.
Am I doing something wrong or is it a fault with the controller or the iPhone? Any help would be much appreciated.

same here. I've got iPone 12 Pro iOS 14.4

Thanks - At least I now know it's not me being a total plonker!
