[IOS] large title starts off hidden or in normal title state ?

as if there is some contentOffset applied.

This only happens in iOS 14. The large title starts off expanded in iOS <= 13.

I know how to fix it but it involves a change RCTScrollContentView class in React Native. Open your project in XCode and paste this code into RCTScrollContentView

@implementation RCTScrollContentView

- (void)didMoveToWindow
{
    [super didMoveToWindow];
    RCTScrollView *scrollView = (RCTScrollView *)self.superview.superview;
    [scrollView updateContentOffsetIfNeeded];
}

- (void)reactSetFrame:(CGRect)frame
{
  [super reactSetFrame:frame];

  RCTScrollView *scrollView = (RCTScrollView *)self.superview.superview;

  if (!scrollView || !self.window) {
    return;
  }

  RCTAssert([scrollView isKindOfClass:[RCTScrollView class]], @"Unexpected view hierarchy of RCTScrollView component.");

  [scrollView updateContentOffsetIfNeeded];
}

@end

React Native Screens has the same issue and I provided them with this same fix. You can see from the issue comments that it has worked for everybody that has tried it.

I don’t plan on submitting a PR to React Native because they won’t look at it. I find the process too frustrating to engage with. But if you want to submit a PR to React Native on behalf of the Navigation router then that would be great.

If the fix works for you then you could use patch-package to apply it?

The FlatList counts as an outer ScrollView (an outer UIScrollView)
