Hi @blacks, I too use a NIKON D5600, I wonder how you feel about the camera?
I like mine, but it has a whole lot of bells and whistles I don't know about.
Mostly I leave it set on Auto, or use the Scene or Effects settings.

I was so VERY disappointed with the "Snapbridge App" which I no longer even mess with. It absolutely would NOT stay paired with between the phone and camera.
I went back to the play store and read reviews; nearly everyone complained of the same thing.
