I was trying to fly in Class B airspace in a zoned area of 100-foot ceiling.  My Phantom 4 Pro v1 would allow me to fly but my Phantom 4 Pro v2 would not.  I ran all the updates for the v2, once that was done it wanted me to log in.  I tried to log into my account as it required, every time I tried it would spin its little circle in the middle of the screen then disappear.  So I would try and log in again, the same thing happened.  Can you please update your geofencing for KSTL?  Or allow the No-Fly Zones window to say yes without having to sign in to your account.  Not everyone has the ability to run a hotspot from their phone like I was able to and still get denied access because it wouldn't sign in.  I am glad my v1 worked or I would have been really hot and had all kinds of nice words.  Last year I was able to fly both versions in this same area.  Please update KSTL area or change the no-fly zone app.

Hello and good day BenjaminCreen. I am sorry for the trouble and thank you for these information and for these suggestions you have shared. I will forward these suggestions to the designated DJI department for further development of DJI. Thank you for your support.

Or maybe you can set the SELF UNLOCK from your home computer,  which requires your AC serial number.

Randy
