I see, in a lot of reviews, that one of the most frustrating comments is not being able to move from a past devotion to a future one. This may help to know: Upon tapping on the app, if you will slide your finger up and down the screen for a couple seconds, by the time the screen with the consecutive dates comes into view you should be able to go back or forward in finding past or future days. It always works for me if I slide up/down BEFORE the current day comes on. Just try it a few times and youll be able to know the right time to do the slide action. Hope this helps.
