My Phantom P3P is currently running Firmware_V_1.6.0040 and I am looking to upgrade to the most recent Phantom 3 Professional Firmware v1.10.90 2016-11-29. 1)  Do I need to update incrementally (Phantom 3 Professional Firmware v1.8.80, then Phantom 3 Professional Firmware v1.9.60 and finally Phantom 3 Professional Firmware v1.10.90) or can I just install Phantom 3 Professional Firmware v1.10.90 and the other updates will automatically be done? I kept the older Version 1.6.0040 due to range issues with the newer updates but am looking to load the most current V.10.90. 2)  My iPAD has DJI GO Version 3.1.7.  Will this cause issues if I try to fly with the older Firmware V1.6.0040? 3)  Are there any major issues with V.10.90?

I have been using the V10.00 for awhile now, no problems, I went from the original software that was installed from the factory which was an older version to the 10.90 with no problem or errors.I know this video is somewhat  dated buy the process is still the same.

I'm wondering the same as I tried from a much older version to 1.10.90 and currently can connect to iOS dji go app 3.1.11.  Now I can't connect.
