I have a phantom 3 standard and the follow me mode will not work. I have used the mode before and it worked just fine. But this last time i went to use it it would not work. I have the drone in the right mode and my phone gps is turned on. There are no messages that come up in the app. When i turned it on and went to follow me mode the drone just sits and hovers that is it but i can make the drobw go up and down and turn it right and left as i should be able to in follow me but still not following me. Please get back with me thanks.
