Official Empatyzer answer
What do active, completed and locked modules mean in microlearning?
In Empatyzer, the microlearning plan distinguishes modules that are currently available, modules you have completed and future modules that are still locked. A lock means the content has not yet reached its release time.
This module-level status is separate from the status of an individual lesson, which can be unopened, read but not passed, passed or locked.
