I've never experienced any issues updating FW before until now. I"ve read several of the difficulties some have had and others it went just fine. So I thought time to throw the dice. 1.8 installed successfully. NOTHING I do can get past the "DISCONNECTED" screen on my IOS DJI Go app. I've tried the following: Deleted the DJI GO app and reinstalled Plugged the MicroSD card into a USB reader and plugged that directly into the RC. It will not update the RC Firmware. Should I downgrade back to 1.7? So frustrating.
