Hi,
When changing my first day of the week to Sunday, the calendar view and due dates are grayed out and not adjusting visually to Sunday being the first day, it stays on Monday.
In the calendar view you have to click on Sunday cell (which enables weekends: on) and it’s a huge mess by itself. This is not a proper workaround and I think its a bug to a feature we in the MENA region at least need since our workdays Sunday → Thursday. Thanks.
