  • Good morning Carey/all,

    I've got a question normally I don't post questions or errors but this time I'm gonna make an exception.

    With updating to 1903 you get various personal settings reset like screens and sound options.

    But the most annoying one is that I have updated 6 laptops in the last week and they all seem to forget the WiFi passwords of earlier connected networks.

    This is gonna be an issue if I want to update all laptops and gonna bring me a lot of complaints from end users.

    Anyone got an idea if this is gonna be fixed or where I can actually place this question/complaint?

    Kind regards,
