DJI have just dropped version 2.8.6 of their DJI go App for IOS. Big addition to this version if the ability to live stream to RTMP servers. This means you could use your own server to stream into as opposed to Facebook or Youtube. A small bugfix of a weak GPS signal being logged in the flight logs.
What’s New in Version 2.8.6
* Added support for live streaming through RTMP Servers
* Fixed incorrect Weak GPS Signal warnings in Flight Record
