I am having no sucess getting the remote controller firmware updated. DJI Go tells me the Remote Control requires Upgrade (v1.2.40)I click on the download button, the Firmware Downloading message appears, and after about 20 seconds i get the Upgrade Package Download Failed.
I have tried the download at home and at work over wifi many times without sucess.

I am using an iPad Air 2.
I rently updated Lightbride 2 to v1.1.70 and the Matrice 600 to v1.00.01.67  with Assistant 2

Does anyone know why the RC firmware is not downloading on DJI Go?

DJI told me to apply the previous Lightbridge 2 firmware (1.1.60). Fixed the problem but not sure why the updated RC firmware cant download. They will look into that.
