Chrome is atrocious. It uses your IP to determine language,
even if your OS is another. You can't completely undo it after install; the default search engine is still the country/language you downloaded Chrome from.
Even funnier is when you get Chrome working in the right language, then do a Google search, the results come up in whatever language Google thinks based of IP, then Chrome offers to translate it.
It's so idiotic.
The Play Store is even worse. Some idiot at Google decided that apps with country restrictions should just 404 when you try to access them. So I downloaded an app for my bank. Go travelling. Get security alert update. Try to update? Nope, app not found. Even though it's running on my phone, I can't get to it via Play. Go to the Play website via a proxy and install it? Sure, that works.
I bet if the responsible people were forced to travel or be expats for a bit, this would get coherent quickly.
