Universal Analytics will stop collecting data in this property on July 1, 2023 (July 1, 2024 for 360 properties). To ensure continuous measurement and customize your data, you’ll need to create and configure a GA4 property before then. When you select this option, if a new GA4 property isn’t created before early 2023, a new one will automatically be created for you. It will include basic configurations based on your current settings and, when possible, it will reuse existing site tags. If you’ve already created a new GA4 property, it will be automatically updated with basic configuration details.
