This may happen due to following reasons:

• A checklist appears just a little before its start time. If you just created or enabled a checklist, you’ll have to wait till the start time.
• A checklist appears on the wall of the assigned person or department, not every wall.
• ‘Create Now’ button on the checklist allows you to create a checklist.
• If you are still having probles, please contact us with the name of the checklist.
