European visitors are being served an old version of the website – because it appears they are getting a site that is resolving to an ipv6 address.
Other countries resolve to the correct ipv4 IP.
My understanding of DNS routing is fairly limited – where can I fix this?
Shopify doesn’t support IPv6 (which may be a big problem for you later) so just remove the old AAAA record. Your DNS records appear to be hosted by “Web-2u Limited”.
