Editing 'disabled' - even though editing is enabled

[Kimbers]

Hi all, 

I have a layer that I cannot add to the Edit widget in Experience Builder. When I look at the hosted view layer in the map, it tells me that editing is disabled, however I do have editing enabled on the layer. I'm using ArcGIS Online

Can anyone help?

Thanks

@bbollin It appears this issue has reappeared. I have a parent layer that is editable and a view that is also editable. ( The view just has less fields than parent). Data Editors are unable to edit the view, but they can edit parent. In the future I want the parent to not be editable, so I need the view to be editable.
