Approximately one month ago I noticed Core Web Vitals was showing under Experience that my sites good URLS’s dropped from 77 to 0 and I’m not sure why. I believe if everything was where it should be the site should have more than 77 Good URL’s. Can anyone provide some advice on how to fix or point me in the direction of a Shopify Expert that might be able to help. Site speed for the site appears to be above average. TBT could use some improvement. Thank you.
