There are two ways to report a bug: in app by clicking on the flag icon (🏳) or using this form: https://docs.google.com/forms/d/e/1FAIpQLSeB38KcbQoKTfhsa3Egmrpj0NXHP9oVlzlYNz2XMVI2gRvm4w/viewform
The in-app flag icon is for reporting audio quality and content issues.
The report form is for more general bugs that you encounter like: crashes, blank screens, content not loading, etc.
