If it has a red line under the word or the sentence makes no sense then you're doing it wrong. I won't judge you based on the pronouns you use (but it won't stop me from thinking that it's bullshit).

My autocorrect doesn't even recognise the word 'autocorrect', let alone any kind of British spelling.

It does, however, accept the singular 'they'.
