I have map on Portal (10.8.1) with four editable layers. I need to add few layers for reference as not editable. Once I do that, the map no longer is able to be taken offline.
The option on the map in FieldMaps "Add Offline Area" disappears. I tried adding not editable layers as MapServer or FeatureServer without editing. In both cases the option for "Add Offline Area" goes away.
Is it by design? Is there a way to have not editable layers in a map and be able to "Add Offline Area"?
