I have bought the Music Studio app for several years now. I currently have version 2.10. Recently, I updated the operating system of my iPhone 7 plus to iOS 13. And I think that update made the app no longer work correctly … It’s more: IT DOES NOT WORK. When I open the app, the keyboard remains extended and small, with long, giant and thin keys. I cannot change the instruments nor can I navigate the app … That is, I CANNOT DO ANYTHING with the app. The only thing is that I can do is get some sound by playing the keyboard, but it is an arbitrary sound, which I cannot choose. The app “freezes” and you can only get ONE sound. I need this to be fixed in some way. And I think I should not be the only one to whom this has happened with the app and with iOS 13. Are you going to update Music Studio 2.10 so that it works 100% with iOS 13? In fact, there has been no news about whether they are preparing any update of the app for those who bought this app. If not, that is, if they are not going to get a new update, I think that, those of us who buy this app, we deserve our money back. Thank you. I am looking forward to your response.
