This has been reported in the past, but the most recent post I’ve found was 2019.
Australian (and presumably other OCE) players get redirected to the EU versions of news posts.
My windows is set to English (Australian) primary, with English (US) secondary, then English (UK), English (NZ), English (India) in that order.
If I swap my windows settings to identify my apps as English (US) primary, I get the correct NA/OCE/SA region version of the news post.
Therefore the website should be set to either fall back correctly when it doesn’t have the client’s primary dialect, or else it should be swapped away from manually equating AU (and presumably NZ & Indian) dialects as UK english…
