We no longer explicitly test with the Phantom 3 aircraft but I can verify that lots of people are using it successfully with the most recent version of the app (4.0.6).
Waypoint flight is different than normal flight. The ability to take off and land manually is about half of the picture.
The IMU initialization warning that occurs in DJI Go is a bit concerning though and is a sign of a hardware issue.
You are never supposed to use two apps at a time. Ever. Unless you do not really like your aircraft very much and are trying to lose it you should only ever run one drone related app at a time.
Michaella: based on everything you were telling me in your emails about it kicking out of the programmed flight mode it is hardware related. Map Pilot cannot kick the aircraft out of programmed flight mode. It is not possible to do with the DJI SDK.
As noted in our emails, we recommended that you look at the log files to check for errors. The DJI Diagnostic column has the flight errors and the App Warning column has the sensor errors. I just pulled one of your logs and it has a TON of Vision System errors that say " VisionSys: Dangerous / VisionSys: Dangerous". More than we have ever seen before. That's bad and is likely the issue. All of your recent flights have that.
