Sentry.init()

  const navigationIntegration = Sentry.reactNavigationIntegration({
    enableTimeToInitialDisplay: true,
  })

  // Sentry integrations
  const mobileReplayIntegration = Sentry.mobileReplayIntegration({
    maskAllText: false,
  })

    Sentry.init({
      dsn: currentConfig.sentry.dsn,
      environment: currentEnvironment,
      tracesSampleRate: 1.0,
      profilesSampleRate: 1.0,
      replaysSessionSampleRate: 1.0,
      replaysOnErrorSampleRate: 1.0,
      integrations: [
        Sentry.reactNativeTracingIntegration(),
        mobileReplayIntegration,
        navigationIntegration,
      ],
    })

Steps to Reproduce

1. Add sentry init as mentioned above
2. add the following to '@react-navigation/native' 's <NaviogationContainer>:

• navigationIntegration.registerNavigationContainer(NAVIGATION_REF)

3. Install the app on physical devices
4. Replays and general errors are working as expected
5. Expects vitals and profiling info on Sentry Dashboard

Expected Result

Mobile vitals should be send to Sentry Dashboard, as for testing we are setting the tracesSampleRate and profilesSampleRate, replaysSessionSampleRate, and replaysOnErrorSampleRate to 1.0.

Actual Result

• Only Replays and general error are being reportes

Hi,
thank you for the message,

can you add debug: true to you Sentry.init and share the log with us.

Hey @krystofwoldrich, I had someone reach out noticing the same problem, they're unable to populate mobile vitals page using the latest sdk version and a basic tracing setup, https://sentry.zendesk.com/agent/tickets/151608. I made a repo to test this out a bit, and followed our routing instrumentation and cannot seem to get my mobile vitals page working with navigation setup - no ui.load spans get captured, instead the transactions just get discarded. In my logs, I am seeing “Sentry Logger [log]: [Tracing] Discarding transaction because its trace was not chosen to be sampled”.
