#TIL what the little colored circles, diamonds and squares mean in Google Tag Manager's preview mode. You can have multiple preview sessions going at the same time on different screens. Each session has it's own shape and color....who knew? Not me.
My latest article covers a "cookieless" scenario on server-side #GoogleTagManager, where you might want to prevent the #GoogleAnalytics4 Client from accessing the FPID cookie under certain conditions.
For example, you might want to support FPID only for a subset of all GA4 measurement IDs collected by server-side GTM, or you might want to prevent FPID access when a custom consent setting requires so.
