I'm using Google Lighthouse to calculate a performance score. One of the criteria is caching static assets such as images and scripts.
I don't have control over all of these, but the ones I do have control over the cache has been set to 30 days. However, Lighthouse is still reporting these as an issue. Lighthouse does report these as having a 30d cache, but still reports as an issue.
What do I need to do to rectify this?
