Hello, I have a Matrice 200 that is prompting for these issues: "cannot take off" in left corner of screem, no battery info available, and compass calibration required (but am unable to do so). The aircraft is flashing yellow. All firmware has been updated and the batteries are working (the batteries function perfectly in another Matrice 200). There was another thread that seemed to address a similar issue - https://forum.dji.com/thread-144270-1-1.html

Any ideas on how to fix this?

Hi Eschreier, after checking your description, I am afraid that you may need to send the drone back for further diagnosis and service.
Please start an online service request on the following page and send the drone back. We'll check the drone when we receive it.
