As an avid VPN user it’s infuriating that multilingual websites insist on using the client’s IP address to determine their language and country when web browsers have been sending the Accept-Language HTTP header since the mid-90s.
I understand that you can work out more or less where someone is located based on their IP address but it was never meant to be a geo-based marker. Why not go the simple route and use the header?
AliExpress in particular is terrible with however they’re going about language selection. I have had this happen countless times and I don’t even travel or use a VPN. Like it’s based on a merchant you viewed or some other nonsense.
