Temporarily freezes on open

Every time I open the app (even if its already running) the list freezes for over 10 seconds and wont let me scroll. In my attempts to scroll, sometimes the app finally starts reacting and interprets the scroll attempt as a "Take Now". I have to edit and delete it. I get the impression its waiting for the ad to load. This is on version 3.8.1, iOS 10.0.2, seven meds in my list.
