We were fetching the query string data from the following cookie. _shopify_sa_p It was working fine until the last couple of days. But suddenly we are not getting the query string data in it anymore on the thank_you page on the Shopify store. Ref parameters that we are supposed to get in _shopify_sa_p cookie are available on all other pages except for the thank_you page. Is there any recent change in the Shopify store due to which this is happening?
