First flight after updating from Fly 1.4.0 to 1.4.2 had the app crash mid-flight on me. Never happened before but I did practice 'controller only' landing procedures in case the Mini ever returns home after a phone crash so my clean underpants were saved. I relaunched the app and it re-connected with the AC, initiating a new flight record mid-air.
Viewed in AirData I observed a record Mavic Mini airspeed of 79.32 m/s, and that was not in a backpack on a superbike
Needless to say, I'm back to ver. 1.4.0, DJI can gladly fly with their own 1.4.2 and duly enjoy their app crashes. I did disobey my own mantra of 'if it ain't broke don't fix it.'
