We apologize for the delay you encountered in hearing back from an engineer but we thank you for your patience.
Azure Static Web Apps is a new product in preview that we just started supporting on Microsoft Q&A a little bit ago. We have taken an action item to add this tag to our internal tooling so we can reply quicker to future issues.
Thanks for asking question! Just to confirm if you have configured the default fallback route. As you need to configure this so that the static web app’s client-side routes work properly and you don’t get a 404. For Vue, you have to add a routes.json file into your public folder.
