Buttons do not work – Draw Review

I used to have this app on my iPad and I thought it was great; I especially loved to draw over my photos. However, I downloaded it on my iPhone to use it the same way but I found out that half of the utilities/buttons do not work. The photo gallery button doesn't work, and the paint brush buttons do not work after I used the fancy glowing brushes. Only the glowing brushes and the artwork gallery buttons seems to work-- which both I'm not interested in. I'm disappointed in this app, and I wished it actually worked like it is supposed to.
