I had Spark and video files copied from its sdcard contained metadata (date, time and gps position), but files from Air doesn't contain this metadata. Am I missing something here?

Spark file:

Have you (if it’s there) turned on the subtitle option in the settings ?

DJI confirmed that the Air does not store any meta-data. I’m using ExifTool to add the create date and going to see if I can copy the GPS data from pictures taken around the same time.
