Yes, as of July 1, 2023, Google has stopped sending hits from Universal Analytics to Google Analytics 4, so users must transition to the newer version of GA4. Aside from the React plugin for GA4, there are other plugins that are compatible with Google Analytics 4. For instance, Gatsby, a popular static site generator that’s built on React, offers plugins that are compatible with GA4. Further, there are also a number of WordPress plugins that support GA4, including “MonsterInsights” and “ExactMetrics”. JavaScript frameworks like Angular and Vue also have libraries that can integrate with GA4. But, it is always a good practice to review the integration documentation and ensure the current compatibility because these aspects can frequently change.
