I tried to made it clear in post #2 and #7.
If you have a good connection between the drone and controller, it won't ask you to select anything.
It should do that for you automatically.
It only does that when there is no connection to the drone.
If the drone is connected, the app will correctly identify the drone and do everything for you.
You need to work on the drone-controller connection because that's your problem.
Who is going to leave a big roof so close to their camera?
My images above show what can be achieved and it's not too bad.
It is what it is ... there are limitations, you just have to live with them.
