The Discover page is the hub from where you can search and find more sources of content on Sharesome. It can be accessed either from the Discover button (on Desktop) at the top of the page.
On Mobile, you can access it by pressing the Search icon. It has a Magnifying Glass icon, and can be found at the bottom of the page, when browsing Sharesome.
We added this to clear up real-estate space on the page. Previously, the Stars and Topics buttons, as well as the Search Bar were displayed on Mobile as they are on Desktop. Moving all of these to the Discover page gave more screen space for us to work with and you to enjoy.
