[UA→GA4] Send analytics.js event, timing, and exception hits to Google Analytics 4

If you collect data for a Universal Analytics property and a Google Analytics 4 property (via dual tagging with analytics.js and gtag.js), you can use a single setting in your Google Analytics 4 property to automatically capture the following Universal Analytics hits:

• Event hits (i.e. Category/Action/Label events that you collect using analytics.js)
• Timing (load-time events)
• Exceptions

This feature does not support Custom Dimensions and Metrics, Enhanced Ecommerce data, or User-ID. If you rely on these capabilities in your Universal Analytics property, we recommend updating your instrumentation in gtag.js or Google Tag Manager to log the necessary Google Analytics 4 fields.

While this setting lets you easily capture these three hit types as events, our recommended best practice is to update your code to capture that behavior using the Google Analytics 4 data model. Learn more
