Update 2/11/2022: does not delete files from camera in video preview mode. Update 8/19/2021: v8.10 quik takes time from the phone and sets time on camera. WITHOUT CORRECTING FOR TIMEZONE. So my videos have timestamps off by 7 hours. Update 8/19/2020: v6.19.1 will NOT sync with my with either of my Hero 3+ cameras. Regression testing is a thing, you know. Your users are not the QA department. Fix this NOW. Previously, I wrote: older version worked fine.... Very disappointed....
