I live in a country which uses a language I don’t speak but Google defaults to regional results in spite of my language being set to English. All other engines give me really poor results (not that Google was giving good ones, the image search has really gone to shit since they started populating it with AI stuff).
I use duckduckgo. One thing I notice about the google language is that my phone has french as the os language so google will be in french but then I go to a computer that has english as it’s language, sign in and google will be in french (even though my account is set to english). So check your OS and browser language settings on all devices you signed in on.
I’m solely an English speaker so it’s not th case for me but thank you for the suggestion.
