Pinterest Button script causing CLS issue in Search Console

Hi,

I’ve been trying to solve my search console average CLS of 0.32 for over a year. I couldn’t understand where it comes from because there were no layout shifts on those pages what so ever. No ads, no consent box shifts – nothing.

Only recently I discovered that it was caused by Pinterest button from Social Warfare. I have lots of traffic from Pinterest and the problem apparently is the fact that when people access the page via Pinterest App and click that Share button generated by Social Warfare, the script that is triggered loads over 3 seconds (it’s very slow for some reason when accessed via Pinterest App). And this super slow response triggers Chrome UX to treat it as a layout shift.

I believe there is a certain time limit in Chrome UX for layout shifts to happen after a button click, so that they are not considered as random layout shifts.

I’ve solved this problem by disabling Pinterest button, so that people save pins from the App instead of the share button, but it defeats the purpose of Social Warfare this way.

Is there any other way to speed up that script?

Thanks,

Roman.
