instant — opted out

The code here is identical to the blocking tab. The only difference is export const instant = false, so no insight is raised — the navigation is just as slow, you have simply said that is acceptable for now.

What to check

In dev, no insight appears even though the blocking tab’s does. In a build, the pending dot still shows on navigation — opting out of validation does not make anything faster.

During a migration you would apply this across the app in one pass with npx @next/codemod@canary cache-components-instant-false ./app, then delete it route by route as you fix them.

Not in the App Shell, so the navigation still blocks. instant = false silences the report, not the cause.
