Hi tommyc, I would really like to understand more about this issue.  We have a lot of different language settings, and they tend to interact in some interesting ways.  Can you please tell me what your browser language settings are?

What is the display language?

What language is at the top of your language list?

What Insider channel and version are you using?

What is your language set to on you operating system?

What operating system and version are you using?

 

Thank you for answering these questions, the answer will help us greatly in understanding what is going on, and will allow us to address it.

 

Thanks,

Elliot

    My OS is Windows 10 version 1903 build 18362.239.

    The region of the OS is set to Belgium, the language is Dutch (Belgium).

    I'm currently using Edge Dev version 77.0.235.5, display language is English. The following languages are configured in Settings:

    1. Dutch
    2. English (United States)
    3. English

    In the JavaScript console, I get the following behavior:

    JavaScript expressionEdgeOpera/Chrome
    navigator.languages["nl", "en-US", "en"]["nl", "en-US", "en"]
    Intl.DateTimeFormat([]).format(new Date())"8/12/2019""12-8-2019"
