I hope somebody has an answer for this problem. When try to set up the follow me function the frame I draw around the subject disappears without the start button appearing. Sometimes it does appear but the frame is now pointing at the ground. Some drift does occur on a windy day. Even on a calm day it does what it wants on its own. Some insight please. While the special functions would be nice to have they are not why I bought the Mantis. All updates have been performed.
