I am not seeing marinas and other points of interest on the ActiveCaptain chart. I turned this on in the chart settings. What do I need to do?

I just bought a Catalina 25. I have synced my phone with ActiveCaptain. I want to navigate to a marina about 20 miles away. I turned on points of interest in the chart settings, but marinas are not showing up on the chart. What do I need to do?
