Microsoft Edge and language setup.
I have three languages, in this order:
English (NZ)
English (UK)
Portuguese (Brazil)
For some reason, sometimes a website loads its Portuguese version, even though PT-BR is my third language choice.
Just today, I was using a website I access every day in English when I clicked a link to another page, and the whole UI changed to PT-BR.
I just removed PT-BR from the list now.
