The app won’t open – Lily - Playful Music Creation Review

I purchased this game hoping it would be fun to explore but I can’t even open it. :( I’m on an iPad and I’ve tried clicking on the app and it just immediately closes out. I’ve tried deleting and re-downloading and that didn’t fix it. I’m not sure what else to do :(
