Don't remember seeing this before. Have not flown for about a week and turned on my Phantom 4 Pro this morning and saw that it required an update so I did that and everything seemed to go fine. I posted something about a few weeks ago where I can no longer calibrate the compass here anywhere close to my home and I get the big red message in the upper left-hand corner of the DJI Go app that says compass calibration error . There is a couple of big satellite dishes behind my house and someone told me that one of them had change directions recently and wonder if that caused this problem. If I take things about a half a mile away from here everything seems to work fine but this morning I noticed this. I was just going through all the settings after the update and notice that Compass number one showed disconnected and I don't know if it actually is disconnected or if it is just because of the compass problem here at my house. Has anyone seen this before?
