I have a list widget of comms records.
I populate each of the cards in the lists dynamically.
The date is set up in US format. How do I change it to MM/DD/YYYY. I'm pretty sure this can be done in arcade.
I can also confirm in MapViewer Classic 10.8.1 my attribute has DD/MM/YYYY.
My PC's region was Australia English.
Chrome was Australian English
Edge was US English.
And Chrome got it right and Edge didn't.
It appears to be the language settings in the Browser, not your PC.
(Can't wait to upgrade to 10.9.1+ and leaving the Map Viewer Classic behind)
I was able to get around this by fixing it outside of Experience Builder in my ArcGIS Online settings for our organisation as an administrator. This worked for New Zealand English. https://doc.arcgis.com/en/arcgis-online/administer/configure-general.htm#ORG_NUMBER_DATE
