RE: “How do people in Europe handle cookies? Are they all set to necessary?”
Not sure I’ve seen any Shopify cookie consent Apps that offer ‘levels’ or ‘categories’ of tracking - e.g. like OneTrust/etc. offer ‘Necessary, Functional, Marketing, Social Media, etc.’ There may well be some such Apps, and if they’re honest then they’d have a rather broad ‘Necessary’ category, that actually translates into ‘Unavoidable because only Shopify has the power to not fire these tracking codes.’
I fear most Shopify merchants ‘handle cookies’ by installing Apps that claim to be GDPR compliant, and even get good reviews… but actually are just useless decorations offering a false sense of security.
