Google announced that support for Universal Analytics will stop after July 1, 2023, as shown in this post: https://support.google.com/analytics/answer/10759417?hl=en. Consequently, any code related to it, like the custom dimensions example given, might start malfunctioning. As a workaround, you will have to adjust to Google Analytics 4 (GA4) and learn how to add custom dimensions there. For those seeking guidance, you can refer to https://jaenal-leegenmao-1.gitbook.io/sakari/playground/upgrade-your-universal-analytics. Remember, this information was released on August 13, 2022.
