P3 Standard with firmware 1.6.80, iPhone 5S iOS 9.3.2, App 2.8.3. All latest as of today June 10/16. It will go into Follow Me mode but does not follow me. Also I tried Point of Interest, and will not circle. It is in the mode as the right (horizontal movement) control on remote does nothing. I know my iPhone's GPS is working as I tested it with a position App. (When I walk watching my Lat Long it updates.) P-GPS works fine. I have not trie IFC prior. Can anyone help me. Thanks.
