Purchased my Inspire 2 the week it was available from DJI. I have the same firmware that is shipped with. It has it's quirks but has been solid since day one. Of course I have a brand new Crystal Sky sitting in the corner because it's not compatible. My I2 is living in its own world because I haven't updated the software on my iPad 4 mini nor the DJI GO4 App. Wanted to get some thoughts about the current state about the most recent firmware. I've read so many threads describing problems after updating and the owners wishing they never did so. Thoughts?
