3
Confirm scope, user impact, and reproduction
Info
Recommended validation or troubleshooting step
Document whether the issue affects one user, multiple users, or multiple devices. Confirm exact error messages, recent changes (password reset, update, network change), and whether the same issue reproduces in web vs desktop workflows where applicable.
