I can only see American date formats. Will the European ones be again added as well? (e.g. 31/12/2019, or even 31 Dec 2019, or even better in the localised AGOL language :-)).
I think as a community we need to have something like this idea
ESRI default date JSON display format across entire suite of platforms
Yup this is planned to be supported and leverage the locale set with your profile/org.
I'll believe it when I see it this has only been an issue since the inception of AGOL I see multiple Ideas and threads about date formats not honoring what should be the default, like it is in all of the desktop applications including the old and new collector applications.
