Attachments() function "Not available"

Question

I have a point feature layer with photos as attachments. This layer was created by uploading the zip file to ArcGIS online per the newest update. The attachments are links to my OneDrive folder. However, in both the symbology and the pop-up configuration windows the Attachments() function is "Not available"...  Why?

You can use the Arcade Attachment function in Calculate Field to calculate an attachment id. Then images can in a popup using that new field. Details are here.

Hi guys,

I have the same problem here. There was another post and someone suggested that I have to turn the syn/tracking enable off in the feature layer setting. I did that and the Attachments function was still grey out and not available.

I wonder if someone can help with this issue. Thanks.

Should be available to anyone with ArcGIS Online, or at least anyone with edit permissions. Here's some info on how to access it : https://www.esri.com/arcgis-blog/products/arcgis-online/data-management/create-custom-field-calculations-using-arcade-expressions/
