Music Studio 2.10 available

Hello can somebody help me please? I installed the new iOS 13.3 update on my iPhone and now for some reason my Music Studo App is unusable on my iPhone X I’m really shocked as I used this app almost daily for years and now it doesn’t work can this be fixed please???

Is it a case i have to wait for Apple to make new iOS software or the creator can update it for the new software.

I have now what it looks like wasted over £10 on this app and I would like a response at least thank you
