I have a long-running problem on Field Maps. When I update the Label (display value) and Code (stored value) on ArcGIS Online, it doesn't propagate to Field Maps all the way. The old code value pops up when I tap the plus button to collect new data. Once I select one of the old, wrong codes, I get the correct pulldown in the new feature and can correct the value, but a you can imagine this is confusing for field staff.
Recently I am also not seeing any symbology next to the old codes, so users can't even pick the right value by consistent symbology.
I have tried changing the symbology and coded values in every nook and cranny of ArcGIS Online I can find, and it hasn't worked.
The old coded values also still pop up when I hit Set Default Style in the map symbology on AGOL, but I can't find any way to change the default style.
