I have a question. I am seeing a message on my tablet which says: Current version of RC firmware does not support in-app firmware upgrading, please upload to version v1.3.20 through USB first. You can download the firmware in Phantom 3 Professional - Specs, FAQ, Tutorials, Downloads and DJI GO | DJI When I visit the DJI website and try to click on the .zip file I get a message which states "Download Failed Safari cannot download this file." I noticed at this link Professional - Phantom 3 Professional Firmware Updates | DJI Phantom Forum that there is a firmware .zip file available yet it appears to be for version 1.4 Is it safe to just download the 1.4, or will I encounter an issue trying to do so? Any advice would be appreciated. Thanks.
