Layout Changes for Records Are Delayed After Save
Where: This change impacts record pages for custom objects in Lightning Experience and Lightning communities. It does not impact record pages accessed on a Lightning console app.
How: To see your layout changes immediately, log out and log back in. Other users don’t see the change until up to 1 hour later when they reload the page. Similarly, they can also see layout changes immediately when they log out and log back in.
This change also applies to record layouts updated through the page layout editor, compact layouts, and Lightning pages. For example, the layout is changed when you add a custom field to a custom object and add that field to the page layout.
For layout changes to a Lightning page, such as via the Lightning App Builder, you continue to see their changes immediately after a page reload. However, other users and other browsers don’t see the change up to 1 hour later when they reload the page. To see the layout changes immediately, users can log out and log back in.
