I had update the fly app to 1.4.12.(1410) last week. Today, I flew my Mini2 to inspect the roof of my 5th wheel trailer. When I fired everything up, it said there was an update. I allowed it to update. Checked the app settings. It now says build 1420. I don't know what it did..update or correct something. I'll have to dig deeper to see if I can see what, if anything, changed. If anyone already knows, please share with the class.
