Please update – Sally's Studio Review

There are glitches in this app where people don't in come in pairs as stated. Also, I have fully upgraded and there are levels, especially lower ones, that I still can't get ultimate. Unsure if glitch or problem on my end. I got an alert that if I update to new iOS, this will no longer work. Please update that and make more Sally games as well as make Sally's hair salon available.
