Ah, the Smart Editor. We've had issues with that on some of our hosted layers in the past. It can be a bit of a pain to reconfigure, but I've always just removed the Smart Editor and re-added it.
To save yourself some time, you can open up the Web App's JSON using the AGO Assisstant and copy the existing configuration. You can search for widgets/SmartEditor to find it easier.
"name": "SmartEditor",
"version": "2.19",
"closeable": true,
"uri": "widgets/SmartEditor/Widget",
"config": {
"editor": {
"layerInfos": [
{
"featureLayer": {
"id": "Well_and_Septic_Layers_9519"
},
You can see that the layer is stored with a specific ID, and that always seemed to be the hangup for us. You can add a fresh new Smart Editor, connect the new feature layer, then save.
Open the JSON in AGO Assistant and paste in the copied configuration from before, but keep the layer ID of the new layer.
