I can chime in throughly on this subject.
I've got a whole video log of my entire experience. However the two up top are the most current and summed up from getting back a beat up used fly more kit to DJI reaching out clacking me and making things right with a new set up.
They are for sure overwhelmed. They are getting 300 or so mavics in a week or possible a day. I can't recall to be honest which it was. And those are just mavics.
A ton of first time users crashing and sending them in for repair. They were not prepared at all. Myself and many seem to see the big problem is the disconnect between support and the repair centers.
Anyway. Check them out. They even sent me a free battery after my first issue. So far so good with the current replacement.
