I just ordered a P4P and am upgrading from a P4. Is there anything different that I need to be aware/careful of other than the obvious upgrades? I use a IPad mini running DJI go 4, and on my S7 edge I use DJI Go 3.0.1 to avoid the maps issue (Will I still be able to use it). I have read about a firmware version to avoid that changes your home point to a random location far away. Any input will be appreciated
