Hi Adam – the Elementor Essentials Course page says “With the upcoming release of Elementor v2.1, some user interface changes are going to happen. Rest assured that this course will be updated after it's official release.”
Elementor is at v2.6.8 as at August 2019.
When will the course be updated to cover the significant changes since pre2.1?
I should remove that notice because I did update the course. But with that said, the course is being completely re-recorded and rebranded Elementor Accelerator. Should be ready by the end of next month.
