When I try and update my fly more batteries after a firmware update and fit the extra batteries to update them it doesn’t seem to be working? When I put in the new batteries and press firmware update it says the firmware is up to date. It doesn’t seem to update the batteries. Any help will be appreciated. Thanking you in advance

Hello there. Thank you for reaching out. Have you already tried updating the firmware using the DJI Assistant 2? Please keep us posted. Have a great day ahead.
