Something you discovered the hard way, but discovered just the same, is the importance of the release notes. It may not work for you, but something I like to do is save each firmware upgrade to a new folder and download the release note PDF's to file for later and continuing reference. Doing so allows me to maintain a progressive record of what changes have taken place over time while providing a known off line location for reference material.
I haven't updated to the over air update version yet but I suspect the system is not yet designed to check for the latest version. It did not prior to the latest firmware upgrades. Realistically, I hope that never becomes the case because if the system auto updates, as another system has done for awhile, a user my quickly find they have new functionality or experience restricted functionality they didn't desire. That's how GEO was introduced into DJI's systems, and worse, installed in an firmware upgrade several versions before it was stated to occur. Those that avoided updating to avoid the installation of GEO found it was installed well before and they were stuck with it. If an owner has a system that functions perfectly for the intended purposes there is little point, as a matter of fact no point, in introducing unwanted functionality or reducing what they are already happy with. Having the latest, greatest is not always a good thing, especially if that newest, super duper upgrade took away from what worked great before. If you do professional work, tool stability is far more important than changing what you know already works for what you use it for. Let the owners decide what they want and install it if and when they want it. They bought and paid for the product, they own it, not the manufacturer, so let the owner decide what they do and don't want and act accordingly.
