How to Contact Support

The quickest way to report a bug or send feedback is from inside the app. Open Settings and use Send Feedback or Report Issue. These forms automatically attach technical diagnostics — your device model, operating system version, and app version — so you don't have to gather them yourself. A problem report can also include the composition you're working on, when you choose to attach it, to help reproduce notation issues.
