Through a server side implementation of GA4 (Google Analytics 4), upon adding a new custom event based on an existing event through the user interface, the event does not appear. Has anyone had an issue with this and what was the resolution to have the data appear? As an example, the event that is already tracking is called, “Button_Click” and there is a parameter called “anchor_text”, where the values for anchor_text are based on the various places that the button could be on a page. This could include, “Menu Nav”, “ATF”, “Product”, “Footer”. Data in the GA4 property is appearing for each of the parameters for the event, “Button_Click”. A new custom event called “Button_Click_ATF” is created through the GA4 interface, where the event_name equals, “Button_Click” and the parameter anchor_text equals, “ATF”. After waiting multiple days, no data for the custom event appears and the new event does not appear in the existing events list. However when GA4 is installed using a tag through Google Tag Manager as an example (not server side), then creating a custom event based on an existing event, isolated to a specific parameter shows no issue.
