Netlify serve old cached version

Hi, @MickPerez. Our service will not cache content that far back and the date: header will still be the present date and time. The fact that you are seeing a date header from a month ago means it is nearly certain that response is coming from a local service worker:

Would you please read that support guide and let us know if removing the local service worker resolves the issue or not?

If it does not resolve it, would you please make a HAR recording of the issue occurring and share that with us?
