Edition theme - Core Web Vitals reports failing URLS

It may not be important, but Google Search Console is reporting that my site’s URLs fail the Core Web Vitals test.

From PageSpeed insights I can see the pages fail on Time to First Byte and Cumulative Layout Shift.

This only happens on the desktop pages, mobile pages are fine.

I suspect this isn’t a huge problem, but would be interested to know if others have encountered this and, if so, how it was fixed.
