hi have only just noticed recently that the mavics barometer not reading properly ,am now out of beginner mode so had lots of flights with it took load of pics etc but yesterday took some shots at almost sea level ,and looked at height on picture and black box data its reading -64.1 metres above sea level but lterally 3 feet above water line some other pictures are the same ,also earlier on yesterday had issues with focusing ie in flight to compose before picture taking green box .tap lightly to focus tapped but didnt respond any ideas .
