Thanks for the info...
Well, waypoints don't interest me, I like to fly for myself, but it's certainly a great feature if you want it...
Is it still ios only too (I've not looked)?
Battery -- well, until DJI replace my faulty batteries, that's of little relevance...
You were very lucky to get battery replacements from DJI; it's not the typical result.
Compass cal was never a problem and I don't fly where there'a a need for a dec fix, and excellent stability can be achieved by tweaking setting as has been documented.
And -- I didn't see the release notes but plenty of people still report video blackouts with 3.06+ so I don't think it's fixed yet!
So I think I'll stick where I am!
