Hi Folks
The default date format in powerapps seems to be mm/dd/yyyy even if your region is set locally in data source e.g. SharePoint.
I changed the format attribute to Text(DateTimeValue(Parent.Default), "dd-mm-yyyy" )
or even just "dd-mm-yyyy" works too

HOwever I also need to print this date in HTML control but it keeps the ShortDate format
I called my data value 'valPurchaseDate' and put it into the HTML control as "&valPurchaseDate&" or as "&valPurchaseDate.SelectedDate&"
and you dont get it format dd-mm-yyyy.

Any ideas how to get the format you want also into HTML ?
Thanks!
