setTimeout not working in Vercel Deployment

[ebulku]

Summary

I am trying to simulate a slow data fetch to test the skeletons, but the setTimeout() function is not working in the deployment, but locally is working fine.

await new Promise((resolve) => setTimeout(resolve, 3000));

Additional information

I have tried both with experimental_ppr and without it.

I'm experiencing the exact same issue. At the conclusion of Chapter 9 of the NextJS tutorial, the delay is working locally, but when I push to Vercel it doesn't have any effect and the revenue chat is rendered immediately.
