What is the url you are testing?

I jump on these forums to help and share some insights. Not looking to be hired, and not looking for work.
Don't hand out staff invites or give admin password to forum members unless absolutely needed. In most cases the help you need can be handled without that.

Absolutely, Shopify has constant problems with this after the Google PageSpeed Insigh update

I have experienced the same issue. with the page speed insights returns "No data" for my store URLs. Shopify IT supported team said its something we did with the header code change. Have you reached out to them?

Hello,

 

The page speed insights site is where this problem occurs. Lighthouse still works in the chrome dev tools. 

 

You can install Lighthouse for chrome plugin/extension first. Then view it using ctrl + shift + I.  Where you can see a new Lighthouse tab. Click the performance checkbox and analyse. 

 

Note : use this in incognito if you have lot of other extensions on chrome.
