A new option just rolled out that allows you to release new content in your Courses on a specific date.
Previously, the drip timing could only be based on a certain number of days after sign-up (e.g. Lesson 1 is released on Day 1, Lesson 2 is released 3 days later, etc.) but now you can say that you want a lesson released exactly on March 25.
This is a great enhancement for organizations that are offering Live classes with cohorts moving through material together, as you can release everyone's new material on the same day instead of being based on when each person signed up.
