Hey guys, I received my mavic on 0300 firmware went to 0600 today and do not love the focus on the camera , and can't use the older go4 app anymore . I do not see anyway to go back to 0300. Only 0400 is the lowest I can go back too. I read somewhere that the 0300 was only shipped with the mavic and was never released as a download can someone confirm this ! Would love to go back to 0300 if anyway possible ....
