I have power cycled the phone, but did so between DroneDeploy updates. Will give that a shot. That said, it "shouldn't" matter
The battery status indication appears to be a communication / API issue between DroneDeploy and DJI.
I've not yet tried "closing" DJI Go before opening DroneDeploy. I'll give that a shot but don't think it's an issue.
Thanks for the DJI GS Pro tip. I'll take a look. I do own the autoflight autopilot app, now owned by hangar, which could do this mission as well. Just a bit more involved setting it up properly.
