Does Google Analytics Mastery cover GA 4?
No, Google Analytics Mastery does not and will not be updated to cover Google Analytics 4 (GA4). The Google Analytics course will be useful for as long as Google Supports "Universal" Google Analytics, which should be through at least the end of 2022. It's still the course we recommend everyone takes to learn GA and pass their certification.
To cover GA4, we've created a new course called Google Analytics 2021, which will continue to be updated as GA4 is rolled out throughout 2021. This new course focuses on a brand new Google Analytics product, which is different/not compatible with the previous version of GA Universal.
