I recently had my MP3 fixed by DJI and now on the RC (they upgraded the firmware for the RC when they sent it back) and fixed the camera transmission.  Since then, in Active Track, the options it shows says "Manual or Parallel".  Previously it said "Trace or Parallel".  Is this part of the new firmware DJI installed ?

Hello there. Thank you for reaching out. You are correct. In the 1.12.4 version of the Fly app, we have made some changes to the naming of certain features to make them more user-friendly. Specifically, the Trace feature is now known as Manual, Follow is now called Hold, ActiveTrac has been renamed to ActiveShot, and FocusTrack is now referred to as SmartShots. Have a nice day.
