The app was showing couldn’t take off, firmware upgrade required, yet it’s on the latest FW, why does DJI assistant show upgrade and not refresh as it does with my Mavic Pro.

I had to leave my flying place and go home and sort it out

Hello there. I am sorry for the trouble this has caused. Can you please try to update the firmware of both the aircraft and the remote controller using the DJI Assistant 2 to see if the issue will still persist? For reference I will post a link where in you can find the DJI Assistant 2 for the DJI Mavic Mini ( https://www.dji.com/mavic-mini/downloads ) and an official DJI tutorial video on how to update the firmware of the said drone. Thank you.
