What you’re saving is a view, not a filter combination. Views on the mobile app are switched via the menu in the top-left when looking at a table (below the main header bar). You’ll see the name of your current view with a small down arrow next to it. That’s the view switcher. Tap that to see other views you’ve saved. Choosing a new view will alter how the records in the current table appear based on that view’s filters, grouping, sorting, etc.
