This is frustrating - whenever I find a third party app to help on conversions / CRM (eg. Klaviyo, hubspot) there's no integration with Squarespace.
Unless of course I take out another subscription to a pocket gouging app called zapier that just seems to do the job that Squarespace should have done.
After two years im seriously considering just transferring everything over to Shopify which doesn't seem to have compatability issues.
I have lots of sunk time and effort with Squarespace however am thinking I made the wrong choice.
