As I mentioned in an earlier thread, I've been away from the p4 advanced all winter and now just getting back to flying. I thought I would review some things and went to the online manual and found two things that appear to be new... tap fly and obstacle avoidance during RTH. According to the manual I need the dji4 app. I downloaded it but as far as I can tell when i open it it just goes to my regular DJI app and there is no tap fly that I can see. And dow the obstacle avoidance apply to my drone?
