Don't Wait Till It's Too Late. Google Isn't Fooling Around.
Google sent out an email early April 2024 to remind analytics users that they'll be sunsetting "all Universal Analytics services and Universal Analytics APIs, which means Universal Analytics properties will be inaccessible through the Google Analytics front-end and APIs."

Come July 1, 2024, you won't be able to "access any Universal Analytics properties or the API (not even with read-only access), and all data will be deleted. While the standard sunset took weeks to complete, the full Universal Analytics shutdown will happen within a week."
If your historical data is important to you, please export your previously processed data before 1 July, 2024.
