Hello everyone, a user of another forum is translating the app into Spanish and he found  a very interesting text line, invisible to the user until DJI  wants:

"New firmware update package is available and required. If now is not the right time to update, please do withing the next d% days. The aircraft will be blocked Until the firmware has-been updated"

I thought that is something we should know before upgrading . DJI could block our aircrafts until we upgrade the firmware. Maybe If you install the firmware 1.9.60 and  app 2.8.2 on android or 2.8.4 on  IOS  we can no longer choose to install other firmware or not .

uuuup!!!!!!!!!
