CLS Differs on Shopify and Page Speed Insights

The CLS of my Shopify Store is currently at 0.41. Largest Contentful Paint is Good ( 1.21s ) and Interaction to Next Paint is Good too ( 72ms )

PageSpeed Insights show me that the CLS of my store is 0.1, which is good… But shows me that the issue are the TBT and LCP.

And btw, this is on mobile. On desktop all the metrics are green. Everything’s good apparently

How should I measure this? What should I do to really improve my stores’s performance and make sure everything is running as smooth as possible?

Should I just take the advice from PageSpeed Insights and on Shopify it will get better too consequently?

Hi @COZYREST

Your website speed changes regularly. I would use the PageSpeed but open your website in the incognito browser. Sometimes, cookies and apps affects the result

It runs smoothly still, for me
