Please make it turn sideway – English Grammar in Use: Sample Review

I’m pretty sure a lot of people have complaint about this problem. I love this app. It costs a lot of money, but I didn’t mind. However, I have this app on my iPad pro, and it does not turn sideways. Please fix this problem. I know it’s a simple fix. Come on, please fix it. You guys charged a lot of money, so it can’t be this stupid.
