I've only reset mine once and it was a while ago. Can confirm it does change the file name numbering. Suspect it also needed calibrating, don't think it needed re-pairing - maybe someone has done it more recently and can report any other consequences.I've never had to hard reset anafi, and the doc doesn't say if there are consequences - does need re-pairing afterwards? Does the file number on the SD card reset? Or all pre-reset settings preserved?
