iOS navigation-bar styling issues


My app has just been approved on the app store but I am having issues with the navigation-bar styling in iOS.
I have ios.css in my native-styles folder.
This is the css

navigation-bar {
  background-color: #3E2F14;
  height: 42px;
  opacity: .5;
  color: #FFFFFF;

navigation-bar title {
  color: #FFFFFF;
  font-size: 14px;
  font-weight: 400;

navigation-bar back-button {
  color: #FFFFFF;
  font-weight: 100;
  font-size: 14px;

It looks perfect in the scanner app but the app store version doesn’t apply the background-color or the color.
Does anybody have an idea why it wouldn’t be showing on the app store version?
Thank you!

Just another thought, does it matter that ios.css isn’t declared in the layout.html head?
