"Create a post" button covers buttons on the bottom-most post
A user reports:
With my Pixel 3 screen, when there's only one photo post to see, the "create a post" prompt covers the reactions and comments bar, so I couldn't scroll down to make a comment or see/add reactions.
On iOS, we added a spacer at the bottom of the scrollview so that the bottom-most post can always scroll up above the "plus" / "new post" button.
