Probably too late given I've only just found your post, but my experience varies with the subject being tracked and the surrounding area. Out in the open, it seems to work fine but tracking an object amongst dense trees etc causes the subject to be lost and the drone will just sit there and hover. Be sure to be in the air at least three metres, in P mode, look for the highlighted subject on the screen and hit 'GO'. I had most luck with the subject being within ten and twenty mtrs.
