I just went though this, did a lot of research, got confusing data and advice.
Finally, chatted with DJI Support, the man asked me what phone or tablet I intended to use, I told him. He said, no problems, update every thing and go fly.
I figured I had to fly it before my return date ran out. I set it up, plugged in the controller and followed instructions as Go 4 4.1.4 said I needed to update, mainly yes, I want to update everything Then it had me calibrate the imu and was happy.
Flew a bit, no problems, had a good time in Beginner mode, so I
Could relax and learn.
Next day, it updated DJI GO 4, to 4.1.5. Again it updated everything, I had to calibrate everything but the imu, did compass out at my site. Flew with no issues, turned off beginner mode and ran a couple of batteries down.
No problems, all working, latest updates and firmware.
Can't tell you what to do though. Not an easy choice I guess?
