Start with the public reproduction project at https://github.com/samirgcofficial/MAUIBug and reproduce the issue in a new .NET MAUI app using a BindableLayout inside a ScrollView. Populate the data after a delay, then test scrolling on iOS 14 and current Android. Done means the ScrollView scrolls reliably after delayed data population on both affected platforms.
