Why does ui load include app start spans?

[MalcolmTomisin]

I want to understand why I might have app.start.cold spans in UI load traces especially when the route isn't an entry point to the app?

Here's the current library I am using:

 "@react-navigation/native": "^6.0.8",
    "@react-navigation/stack": "^6.2.0",
    "@sentry/react-native": "^5.33.2",
    "@sentry/utils": "^8.55.0",

Here's how I am initializing Sentry Client

export const navigationIntegration = new Sentry.ReactNavigationInstrumentation()

export function createSentryClient(App: any) {
  Sentry.init({
    dsn: Config.SENTRY_APP_URL,
    environment: Config.ENV_NAME,
    integrations: [
          new Sentry.ReactNativeTracing({
            routingInstrumentation: navigationIntegration,
          }),
        ],
        enableUserInteractionTracing: true,
        tracesSampleRate: 0.2,
        profilesSampleRate: 0.5,
        enableAppStartTracking: true,
        enableNativeFramesTracking: true,
        enableStallTracking: true,
        normalizeDepth: 10,
  })
  return Sentry.wrap(App)
}
