Hey everyone. I am trying to update to the latest firmware form the DJI GO 4 app. It gets to 39%, the aircraft restarts, then the update fails. I have tried restarting everything. I tried deleting and reinstalling the app. I've even tried different iOS devices. Firmware version is V01.03.0200. Using iOS 10.2  I'm sorry if this question has be asked before, but I searched around and couldn't find it. Thanks in advance.

Hello BrandonA614, please try to do the update via DJI Assistant.
Here is the video tutorial for your reference.
