I seem to be having a lot of issues so I am going to join up and ask for help. I suppose I am not unique in that from what I have been reading as a non-member. I just got my unit today, I did some updates and now I can't seem to get my spare battery updated. It doesn't work properly in the Phantom 4 since I updated the unit and the DJI Assistant 2 software doesn't seem to do anything at the moment. I have not yet flown the craft yet, I am taking my time before I actually try to fly. So far it isn't going well. Oh well, I just wanted to introduce myself as a new member and hopefully I will be around a long time. Thanks
