+This is by design when instrumenting Single Page Applications (SPA). See the following [GitHub issue](https://github.com/microsoft/ApplicationInsights-JS/issues/1139). 
 
 Different workarounds exist: 
 
-- Manually calculating the duration between different route changes in the app and feed that duration value into the trackPageView() method. See details [here](https://github.com/microsoft/ApplicationInsights-JS/issues/1139#issuecomment-566169033).
-- The methods startTrackPageView() and stopTrackPageView() can also be used as timers to calculate page load durations. See details [here](https://microsoft.github.io/ApplicationInsights-JS/webSdk/applicationinsights-web/classes/ApplicationInsights.html#startTrackPage).
-- Sample app measuring duration for SPA app can be found [here](https://github.com/microsoft/applicationinsights-react-js?tab=readme-ov-file#example-of-measuring-page-duration-in-an-spa).
-- You can set overridePageViewDuration. See details [here](https://github.com/microsoft/ApplicationInsights-JS#:~:text=overridePageViewDuration) to manually set/override duration.

-The `correlationHeaderExcludedDomains` configuration property is an exclude list that disables correlation headers for specific domains. This option is useful if you include headers that cause the request to fail or not to be sent because of third-party server configuration. This property supports wildcards. Therefore, you can specify a value such as `*.queue.core.windows.net`. Avoid adding the application domain to this property because this stops the SDK from including the required distributed tracing `Request-Id`, `Request-Context`, and `traceparent` headers as part of the request.

-If the SDK reports correlation recursively, enable the configuration setting of `excludeRequestFromAutoTrackingPatterns` to exclude the duplicate data. This scenario can occur if you use connection strings. The syntax for the configuration setting is `excludeRequestFromAutoTrackingPatterns: [<endpointUrl>]`.

+## I'm experiencing connectivity issues between my application host and the ingestion service
 
 Application Insights SDKs and agents send telemetry to get ingested as REST calls to our ingestion endpoints. To test connectivity from your web server or application host device to the ingestion service endpoints, use raw REST clients from PowerShell or [curl](https://curl.se/docs/manpage.html) commands. For more information, see [Troubleshoot missing application telemetry in Azure Monitor Application Insights](../investigate-missing-telemetry.md).
