Same problem - latest version DD installed for ipad Mini 2 - app crashes, goes to home screen, but drone continues flying its path. Restarting DD but need to login to get back to screen (challenging when no internet access and very dangerous too I think). No idea if taking photos or not or if true to course or not. Very dangerous! I let it continue and at 20% battery auto initiated RTH. Issue began today first flight since last DD update and with latest firmware on DJI Inspire Pro 1. I don't have any other mobile device to compare with. Occurred about 5 min into a 15 min planned flight. All soft and firm ware up to date.
