Bulldog Children's Books

I really want to use this with my five-year-old granddaughter, but I don’t know how to use it with voiceover. I contacted the developer when I was in the trial subscription and got no response. I went ahead and subscribed, because I really would like to use the app. I get to the library and then I tap my finger all over the screen and voiceover is turned off. I turn it off and then I get a book somehow. I can’t read it though. Only the title is there the author and illustrator and it won’t save to the library. Five stars if I can figure out how to use it or get help from the developer. Maybe it needs an update.
