switching from front to back camera on ipad pro 4th gen

When you open the camera app, look for an icon, which is shaped like a camera with a circular symbol inside. Tap it and you move from front to back, tap it again and you move from back to front.

That's odd. On my iPad Pro 11, the circle with arrows is inside a camera icon on my iPad Pro 11, but that was also in landscape mode, not Portrait. Maybe that makes a difference? I won't be able to check till I get home tonight. Either way, it worked and that's really all that matters.
