Does anyone know the right way to install klaviyo on a shopify store that optimises performance? I've complained to Klaviyo that loads of scripts are installed and it impacts performance (a big no-no now that Google launched web vitals especially) and they send me to this page. But that method still injects loads of scripts, and doesn't even sync a shopify customer list with klaviyo profiles.
Specifically that method adds 8 scripts and 1 stylesheet (and this is without the shopify app intalled)
Tests before and after saw my store drop from 88 to 48 in google page speed insights (desktop) and from a B (88%) in GTMetrix to a D (56%).
It's just not sustainable to have this impact on performance and I'm reaching the end of my journey with Klaviyo unless someone can add some input to help.
