| ### Support for custom spans and attributes: | ||
| While automatic instrumentation covers the platform interactions, we know you need visibility into your own application logic too. We're working to support the [OpenTelemetry API](https://www.npmjs.com/package/@opentelemetry/api) to make it easier for you to instrument custom spans within your application. | ||

Can you add a section here explaining Missing Root Spans/Trace in progress so I can link to it from the UI?
