Thank you for your willingness to correct this problem. Happy New Year.

When I reinserted the USB cable in the opposite direction nothing happened. When I press the grayed out Metering button on my iPhone this message is displayed "metering in not available. USB is not active". My order number was #14467. Thank you - Peter

I am having the same issue using my iPhone X and my Nikon Z6. Pressing the faint white Photo Review on the iPhone app does not reveal a toggle to turn on Photo Review.

Hi Paul, You did make sure to turn on image review, right? - on the photo screen, tap on the thumbnail icon in the bottom right, then select "on" in the grey box, above the "clear all photos" button. Take another shot after that, and make sure the Unleashed doesn't go to idle before the image start...

I received my Unleashed N2 this week. Everything is working wonderfully except I can't display photos on my iPhone. The cable is plugged in properly. Does anyone have any suggestions? I have watch the video tutorial on Youtube and I know the USB port on my Nikon is working properly. Thank you.
