I got a downgrade note on DJI Assistant2.
Should I do the downgrade?

Hi thank you for reaching DJI Forum, we do not recommend to downgrade the firmware not unless you are trying to update the firmware and did not go thru, the only time you are going to downgrade is when you are having problems with updating the firmware to the latest update . Meaning to say you could try to downgrade first to the oldest firmware before proceeding to the latest one. Hope this helps

Por favor, nao devemos atualizar o Phanton 4 Advance + ?? ouvi dizer que estao caindo apos atualizacao devido a problemas na bateria. ???
