Answer 1

The reason it might not scroll down up is your content doesn't needs scrolling as it fits inside the screen size.For that you can try adding more items or define height for any of the scroll view large enough to make it scrollable. Other then that it does scroll horizontally for sure. Also you should try to use Nested scroll view that is a much better way as mentioned in the link in the comment.
