If you don't like errors from PageSpeed ​​Insights
Then you need to be more specific here.
For example, the Yandex and Google metrics must be downloaded and called on the server itself.
And make the crown auto-update, for example, once a day.
If the Yandex metric is not cached. it will be 99/100.
In general, about caching, I advise you to make your own cacher if the pages are static.
