Not sure what's going on. The machine works fine, but I can't do a quick transfer. I can connect to the machine with my iPhone 14 (with DJI Fky App), but when I try to download, it doesn't ask where I want to save the material, and it just gives me the spinning wheel of death, and then boots out after about 3 minutes.

Hi there. Thank you for reaching out and we're sorry for the trouble. Please try to follow the methods below and see if the issue persists. If yes, please upload a screen recording showing the issue so we can check it further. Please keep us posted. Thank you.

Method 1: the mobile device is not connected to the DJI RC-N1 remote controller.
1. Power on the aircraft and wait until the self-diagnostic tests of the aircraft are complete. Quickly press the power button three times to switch to QuickTransfer mode. The aircraft status LEDs will blink blue once switching is successful.
2. Make sure Bluetooth and Wi-Fi are enabled on the mobile device. Launch DJI Fly and a prompt will appear to connect to the aircraft.
3. Tap Connect. Once successfully connected, the files on the aircraft can be accessed and downloaded at high speed. Note that when connecting the mobile device to the aircraft for the first time, you need to press and hold the power button for two seconds to confirm.

Method 2: mobile device is connected to the DJI RC-N1 remote controller
1. Make sure that the aircraft is connected to the mobile device via the DJI RC-N1 remote controller and the motors have not started.
2. Enable Bluetooth and Wi-Fi on the mobile device.
3. Launch DJI Fly, enter playback, and tap in the upper right corner. Switch to QuickTransfer mode by following the prompts in DJI Fly. Download the files on the aircraft at high speed once switching is complete.

• Ensure that the mobile device’s Bluetooth, Wi-Fi, and location service functions are enabled before conducting QuickTransfer.
• When performing QuickTransfer, there is no need to enter the Wi-Fi password on the mobile device’s settings page for connection. When you launch the DJI Fly app, a prompt will be provided.
• Please perform QuickTransfer in an environment free of interference and obstacles, and away from interference sources such as wireless routers, Bluetooth speakers and headphones.

The real answer is you have the tap the power button on the mini 3 3 times until the leds turn blue. Honestly I have zero idea why they don't tell you this in the app
