Is it just me or did the Mavic do some extra stuff during this upgrade?
By the end of the process (around 75%) it suddenly moved one propeller (like it does at startup, but only one) and did the "DJI sound". A few minutes later, it did the same but with another prop. A couple of minutes later it restarted and moved all four props as usual and the upgrade finished. As far as I can see everything works fine, just never noticed it doing those extra prop movements during an upgrade before?
Also, it upgraded the firmware of the battery, so I guess there are some fixes in the update not mentioned in the release notes (as they are not really talking about anything that seems to have with the battery to do)
