When viewing the ArcGIS Online Organization home page on mobile, the featured gallery 'Load More' option just spins and never populates more items when clicked.
View the full site to see the gallery as it is shown on ArcGIS for Desktop and all items in the gallery is visible.
Note: The Explorer for ArcGIS mobile application only shows 10 items and does not show all items in the Gallery. It does not display the 'Load More' option.
