To check the version of Google Analytics that you are using, follow these steps:
Note that if you are using the latest version of Google Analytics (Universal Analytics), the tracking code snippet will use the "analytics.js" library. If you are using an older version (Classic Analytics), the tracking code snippet will use the "ga.js" library.
@dudley You can check the Google Analytics version by going to Admin, and then under the Property column, select Tracking Info. Then, click Tracking Code. This will show you the version of the current tracking code.
