With the Assignment Deadlines Pro plugin for LearnDash, you have full control over whether students can submit assignments after the deadline. By enabling submission restrictions, you can prevent late submissions and maintain a structured learning environment.

To enforce submission restrictions:

• Navigate to the Assignment Uploads section in your LearnDash course.
• Open the Assignment Settings.
• Enable the Assignment Deadline feature.
• Choose either Manual or Automatic deadline type.
• Toggle the option to restrict submissions after the deadline.
  Save your changes.

Once enabled, students will no longer be able to submit assignments past the due date—ensuring discipline and timely progress in your course.
