I'm using computers since Windows 3.1 incarnation, but never paid much attention to what's going on under the hood. My both birds (I1 Pro and P3P) are hibernating now, batteries 50% charged, iPad Air 2 sleeping - all waiting for warmer season and better weather to fly. Every 2-3 weeks I wake them up and exercise a couple of sim flights just to stay in shape. Recently, however, I noticed some changes in DJI Go UI. About section revealed new version (2.7.1). Is it possible that the app upgraded itself without my knowledge? The alternative scenario: I did the upgrade, but don't remember (early stage of Alzheimer's disease).
