Where did the NOAA charts layover go? – Boat Watch - Ship Tracking Review

I have used this app for months and loved it. It is a valuable asset for doing my job. I especially loved the NOAA chart layover. Yesterday, when I wanted to use my app all of a sudden the NOAA charts were gone. Restoring purchases didn’t bring them back, reinstalling the app didn’t do the trick and I don’t see any option to select the NOAA charts layover as I was able in the past. Please help!
