I use Australian English and when composing an email, it marks some words as being wrong when they are correct. In the sentence “I realise the colour of the licence isn’t always aluminium grey.”, it marks “colour” and “grey” as incorrect and suggests the US spelling, despite not marking licence, aluminium or grey as being wrong when that is not the US way of spelling them. (See screenshot for more clarification).
I don’t think the particular combination of words that Mailspring thinks is correct is a form of English anywhere.
It seems to happen if it’s set to either “Use system language” or Australian English
Steps to reproduce the behavior:
- Set language to be Australian English
- Use the following sentence
Nothing is marked as incorrect besides the “youyy” which was intentional
