The current Google Analytics system (called “Universal Analytics”) will stop working in July 2023, so everyone will need to upgrade by then. In most cases, the upgrade is very simple. For those who use a lot of advanced Analytics features, it may take a little more work. We’ve been transitioning our clients to this new system, and will continue into the new year. If you use a different service to manage your Google Analytics, make sure they get you transitioned in the next few months.
