“....have until the end of June to switch to a supported language”
That’s ok then. I mean, who can’t fluently learn a new language in a month? Duh!!
Oh, and of course you need to tell everyone you might be writing to to do the same. Otherwise they won’t be able to read your letters.
It’s bad enough when “English” is taken to mean the Americanised mangled version, with no option to change it to real English.
And in true MS style, “consistency” is taken to mean “lowest common denominator” (because we can’t be arsed to do a decent job of it)
