Attachments() Function in Web Map Symbology

Question

I am trying to set up an arcade expression in the layer symbology that will differentiate features with and without attachments. The Count(Attachments($feature)) part works great in a popup attribute expression and returns the necessary values but I am getting an error when trying to use the same code in the symbology expression. It is saying 'Attachments' is not defined.

Here's my code:

If(Count(Attachments($feature)) > 0) {
      // if count is greater than zero there are attachments
      return 'Has Attachments'
  } else {
      // otherwise the feature has been inspected but missing photos
      return 'No Attachments'
  }

The funny part is, if I click run to test, it gives me the correct output but the Done button is grayed out.

First time Arcade user here trying to do the same. If Done button is greyed out, does that mean the code is incomplete?

It's 2026, and still can't visualize using Attachment function, very disappointing, since it used to be possible

Map Viewer still doesn't allow for the Attachments field to be used in symbology; however, I have begun creating a field called something like "ItemsAttached" and calculating that field in AGOL using Arcade to say 0 if there are none and then 1 for a yes.

Here is the arcade that I use when calculating:

var hasAttachments = Count(Attachments($feature)) > 0;IIf(hasAttachments, 1, 0);
