i was trying to drag the camera and it dont work (at least for me)
By drag do you mean pan the camera left/right/up/down like you can do on PC by right clicking?
Furthermore, I managed to do it a couple of times but it is very difficult. I think it could be to do with the threshold of movemet the fingers have before triggering zoom instead of translation of the camera.
For some reason it works perfectly in the editor for me though. It's only in the flight scene it doesn't work.
