Unable to restore purchase :( – DEEMO Review

This is one of my favorite apps of all time and has been for over four years! But trying to restore my forgotten hourglass purchase doesn’t do a thing and I don’t know what to do. Also can’t restore my data. Do I have to unlock it all over again? I don’t mind too much— it’s a great game, but it’s a little disheartening.
