I have a dark background and the initial look of the nav bar is showing like there is a light background. See picture. Has anyone experienced this or know of a solution? If I scroll the table up, it will fix itself and start behaving as I'd expect.

Prior to iOS 26, we could set the color of iOS's back button (at left of nav bar) using the line: navigationController?.navigationBar.tintColor = UIColor.red This is not working for me in iOS 26. Anyone get this to work? We can change the tintColor of individual toolbar items that we add, but the back button is system generated.
