Wont show % after 1 yr on free version

What changed between 7.16.15 and 8.4.15? Yes, I track my daughters growth with EVERY appointment! Now I have to pay to see my childs percentages? A bit ridiculous if you ask me. $2.99 is not a bad price, but why should I have to pay for something that has always been free? Perhaps its time to find a new and better free app. Too bad, I liked this one.
