How do I put a published meal plan back to draft?
Meal plans use statuses: Draft (not visible to the client), Local changes (edited but not visible to client), and Live (visible in the client's app).
If a plan is Live and the client should no longer see it, remove it from the client with Unassign Plan.
How to:
Go to the client's profile → Nutrition
Select the plan in the dropdown (if the client has more than one)
Click ⋯ Actions
Choose Unassign Plan
The plan is removed from the client's app immediately.
In conclusion: Unassign keeps the plan in your system as a Draft; Delete Plan permanently removes it and cannot be undone.
