First, I want to say Hello....I'm new to the forum, but not brand new to drones, although, I consider myself pretty green, (rookie), especially when it comes to the Mavic Pro. I just bought one used for a very good deal. The original owner bought it about a year or so ago, and it apparently, hasn't been updated. After setting it up, it says:Update needed. From all the scary update reviews I've read about the last two updates for the Mavic Air, I'm hesitant, to say the least, to update without some kind of confidence on it. I'm especially concerned when you can't go back to the earlier updates, in case this "new one" gives us problems. The other issue I'm having is, if I don't update, how can I get rid of the Update needed message on the DJI Go 4 ap? I'm also getting a no fly zone error, so I know I'll have to move to a legit fly zone in order to test the drone out. I'm not sure if the "update needed" message is for the Go 4 app or the AC. Probably both, but I guess the bottom line, or at least most important part of this "lengthy" post is: Can I trust updating the drone to the "latest greatest" firmware, or should I try and stick with what's in it.? At this point, I'm not sure how to read or find out what version is in my AC. Thanks, for any help on this, and I'm sorry if this is a redundant question. I searched the forum, but couldn't seem to find the answers I needed. Marc Trainor.
