Lightning page activation and assignment
Key Takeaway
A custom Lightning page does not reach users until you activate it. Record, Home and app pages each offer different activation options.
Activation controls who sees a custom page built in the Lightning App Builder, and in what context. You can activate a page for the whole org, for specific Lightning apps, or for specific combinations of apps, record types and profiles.
How to activate a Lightning page
You activate a page from the Lightning App Builder.
If the page is ready...
Open it and click "Activation".
If the page is new or changed...
Click "Save", and then click "Activate".
Creating and saving Lightning pages requires the "Customize Application" permission.
You do not need to activate a page again after you edit it, because clicking Save pushes the changes to users.
