I have a problem with the Mavic Air 2 Drone
I removed the drone from my account because I wanted to sell it.
The new buyer has created an account and when trying to connect (adding the drone to the account), information pops up that the drone has outdated software. The software is current 01.01.1300 - there is no newer download. I also did a refresh of this firmware and nothing. Constant message when trying to add a drone as above that the drone's software is not up to date. What can I do? Is it necessary to add a drone to the account? I also deleted Cashe memory in the DJI FLY app.

Tried everything on different devices (ios, android). Please help.

Hello there! Thank you for reaching out. We apologize for any trouble this has caused. Could you please update the firmware of the aircraft and try uninstalling and re-installing the DJI Fly app? If the issue remains, could you please send us a screenshot of the device management page? We await your feedback. Thank you!
