App not auto rotating

All,

XCode 9, IOS 11.2 build.

I have an app that was setup to run on the I-phone/I-pad.

The Iphone only has the Portrait orientations in the info.plist file and in the build-->General settings. it only has Portrait check boxes selected.

It was Auto-Rotating at one point.

I was working with the contstraint (man those things are terrible).

And now it won't rotate for the Iphone (like if I had turned the rotation lock on the phone to "Locked" it's no though, it's off).

this happens in both the simulator as well as on my Iphone.

It displays correctly with the home button at the bottom, but when I turn the phone upside down, The banner stays upside down at the bottom.

It works fine on the Ipad though.

not sure where else to look or what else to do.

I have no code that touches or does anything with the UI view controller other than constraints.

I just want to get it back to the point that if I turn the phone upside down the app auto-rotates to have the banner back at the top.

Any help would be appreciated.


Thanks

Matt P.
