I have configured a pop-up in AGOL with a subtype code in the title. It shows properly in the web map, but Explorer shows the code and not the value.
I see you had this problem about a year ago as reported by Brook Bourgeois.
I am experiencing this on an iPhone 7 running iOS 11.4.1 and Explorer 18.1.1 build 2178.
Terry,
Can you share a bit on how you set up your subtype and domain with codes used?
I did a simple test with Integer field 1, 2, 3 one, two, three. and Explorer is showing the Label.
