Field Maps Layer Group - Unique Symbol Colors Not Propagating to Edit Menu, Templates, or Field Maps iOS App (Lines Layer Only)

DerekClifton

I created a Field Maps layer group using the default template, consisting of Points, Lines, and Areas layers. I added this layer group to a web map that also includes other non-Field Maps layers.

I have configured the categories, domains, and code values to align with the layers' styling under Styles > Unique Symbols. The default "Category 1," "Category 2," etc., are now properly labeled to match the domain descriptions. Each feature (points, lines, areas) has specific symbols, colors, and text labels assigned.

These symbols and colors display correctly in:

• Styles > Unique Symbols
• The map legend
• Layer properties

However, the Field Notes (Lines) layer is not behaving as expected:

• In the web map's Edit menu, the symbology for all three Field Notes layers is shown separated by layer name. The categories are correctly named (from the template), but the line colors appear as black/gray instead of the configured colors.
• In the Field Maps iOS app, when creating a new feature, the line options also appear gray (text labels are present, but no colors).
• This issue started this week; previously, colors displayed correctly in both locations.

Troubleshooting attempted: I tried switching the styling from Unique Symbols to Single Symbol (and back), then reselecting the "Category" attribute and reconfiguring each category's line symbol and color. However, when accessing Configure > Templates in the web map, there is no prompt to sync changes, and the lines remain gray.

I've attached screenshots for reference:

1. Layer group properties (Field Notes (Lines) section shows correct colors): https://imgur.com/hPg4u5I
2. Web map > Edit menu (Field Notes (Lines) lacks proper colors): https://imgur.com/3E1v7Fb
3. Web map > Configure > Templates (Field Notes (Lines) lacks proper colors and symbols): https://imgur.com/YXRidgy

TL;DR: The unique symbol styles (colors) for the Field Notes (Lines) layer are visible in the layer properties and legend but are not propagating to the web map's Edit menu, Configure > Templates section, or the Field Maps iOS app. This worked correctly until recently, with colored lines appearing in all these areas.

Any assistance would be greatly appreciated! Thank you.

Thanks for info, very helpful.

>Check the Field Maps Web Designer: Go to the Field Maps web app (not the mobile one) and open your map. Look at the Content tab and click on the Lines layer. If they look gray there, you can fix them in the Templates section of that designer. It's often more reliable for pushing changes to iOS than the standard Map Viewer.

After poking around in the Field Maps Designer, deleting every existing custom "Category" it finally prompted to resync at which point it repulled the symbol and color renaming them to default "Category 1", etc.   after renaming and checking the main Main Web/edit/etc. the colors had returned. 

Thanks!
