ListView vertical scroll randomly not working in native app

I have a listview placed in a container. Page size is set to 3 and total data is 5-7 items. But sometimes scroll works and sometimes it only shows 3 items with no scrolling and no “load more” button. Usually it does not work on first page load and after subsequent reloads of app, the scrolling on listview works. What could be reason behind this behavior? How to configure scrolling behavior of listview in a native app?
