Josh (tech writer) has reviewed and suggested new wording.

Do not alter or remove anything below. The following sections will be managed by moderators only.

Acceptance criteria

• Update the current text below the main heading to the following:

Google Analytics 4 is the newest version of Google Analytics. It will replace Universal Analytics on July 1, 2023. After that, Universal Analytics properties will no longer collect new data.

Implementation Brief

• Update the text/sub-heading of the GA4 activation banner per the AC

Test Coverage

• No tests needed/VRTs should be updated, if needed.

QA Brief

• Trigger the GA4 setup banner (one way to do this is to set up a new site, then manually delete the googlesitekit_analytics-4_settings row from the wp_options table in the site's database)
• Check that the new text from the ACs appears in the notice.
  • Note: Only check for this text change, don't compare design elements from the screenshot in the issue to the plugin.

Changelog entry

• Update wording regarding the date Universal Analytics will stop collecting data.
