Universal Analytics (UA) is deprecated. For details, see #1096. Here's some of the code associated with the page feedback feature:

This still uses the analytics.js library's ga() function. Note that this code is incompatible with GA4 because of the library that is used and the event name, as is explained below.

Tasks

• Migrate from analytics.js to gtag.js - Use the gtag.js analytics library by default #1177
• Enable page feedback even without a Google analytics ID #1727
• Fix event emitting code that calls gtag - [GA4] Emit page_helpful events for page feedback #1726
  • Confirm that page_helpful events are being emitted, with a default value of 100 for "yes" and 0 for "no" responses:
    • For docsy.dev
    • For example.docsy.dev
• Add entry to the CHANGELOG
• Update the docs, Access the feedback data in particular - [GA4] Emit page_helpful events for page feedback #1726
• Add a comment to "Helpful" event not registering in GA4 #1426

Notes:

• Interestingly, Kubernetes docs had switched to using gtag.js in their override of layouts/partials/feedback.html already 4 years ago
• Indirectly related:
  • i18n of page feedback #175
