Map Pilot Pro not working with DJI mini 3

A mission with mini3 seems to work good, as the drone flies along the path and remote control beeps at the end.   HOWEVER, at the end of the path it hovers at the flight altitude and does not come to the starting point.  Must swithc to "sport mode" and back again to recover manual pilot.

More important: It takes one picture (the landing path) when it takes off, and then no other picture is taken. Both "active connect" ON and OFF have been tested with the same result

I can live with the first default, but the app is useless if I get no image from the land to map. 

Does anyone have the solution ?
