I have added more information

Thank you for your answer. Our root view navigation bar has added the APP logo image as a titleView, and we have also added a view on the bar of the navigation bar as needed. Every time we return to the root view, we need to display this view. However, on iOS 18, the logo will be overlaid on the view at the moment of returning to the root view, only for a short moment. Normally, the view should always be overlaid on the bar. I want to solve this problem.

Thank you for your answer, it has been very helpful to me

Thank you, I have confirmed through investigation that it is a network issue. so sorry
