SharePoint Online - Promoted Links Nuances

1. By default it will create a very limited view of the tiles that only spans horizontally. It will be limited to a maximum of 30 items. You also can not modify this view. To get around this maximum item limitation create a NEW standard view. Modify the new view to meet your needs.
   
2. The tiles will only scroll horizontally. A simple fix for this is to add the following CSS to a custom page via a script webpart. This will target the promoted links webpart by hiding the arrow navigation and forcing the tiles to be a bit more responsive.
