Apologies for bad explanation. Maybe I was looking at an old version tutorial. In such tutorials in order to access the other preset modes the explanation said click on the drone icon which was underneath the take off and RTH icons on the left of the screen. It was like looking directly overhead a drone showing 4 small circles It is this icon I was looking for. I have just tried connecting the phone only without controller. When I do so now underneath the two icons for take off and RTH on the left I get a small icon like a controller. When I click on this in non controller mode i.e just connecting wifi with the drone I do get the other preset modes like tapa fly etc. I have tried two phones and both show this small controller icon when connected non controller wise. When I switch back to the controller i.e. connecting GO 4 app to the controller. Initially whilst the Mavic is switched off in controller mode I can see the small controller icon under the take off and RTH icons. However when I switch on the Mavic and it connects ready to fly and with the camera showing me a picture the small controller icon disappears. I obviously must have something switched off in the menu somewhere.
