 ### Duplicate `page_view` events in GA4
 
-If you are sending multiple `gtag(‘config’)` commands called from Set Configuration mapping on one page before a new DOM has loaded, and you have defined `send_page_view: true` with each ‘Config’ event, you may see duplicate `page_view` events sent to your GA4 measurement id. If this is the case, please refer to Google's documentation on [Ignoring duplicate instances of on-page configuration](https://support.google.com/analytics/answer/9973999?hl=en#:~:text=as%20described%20below.-,Ignore%20duplicate%20instances%20of%20on%2Dpage%20configuration,Click%20Save.,-Give%20feedback%20about){:target="_blank"}.

 If your site is a Single Page Application (SPA), you may want to leave the **Ignore duplicate instances of on-page configuration** toggle disabled in the Google Tag Admin as a new DOM is not called on each new page path. If you have a SPA, disabled the **Ignore duplicate instances of on-page configuration** toggle, and have multiple Set Configuration mappings, use Segment's new **Send Page Views** field mapping to override the `send_page_view` parameter in your Settings. This selection takes precedence over what is defined in the Segment Settings. If you leave the selection for your destination undefined, it will fall back to what you selected in the Segment Settings.

 ### My Events Send to the wrong Google ID
 
-In each Event Mapping, there is a “Send To” parameter. Set this to “True” if you would like to include the send_to parameter and only send the event to the measurement_id indicated in the settings. If you select “False” or do not enter a selection, GA4 Events will broadcast to all measurement IDs, including Google Ads IDs, on the page.
