Hello.
Today (12/9/2021) i created a new hosted feature layer in AGOL with the December updated process for creating views (https://doc.arcgis.com/en/arcgis-online/manage-data/create-hosted-views.htm). The view was created successfully.
I went into the 'Settings > Feature Layer (hosted, view) > Editing' and selected Enable editing and saved changes. When I added the view to an existing AGOL web map (using Map Viewer Classic), the view is not editable.
In map viewer classic, when i click on the 'configure pop-up' button, the checkbox to enable editing of each attribute is not visible (only the 'Display' checkbox is present).
I have verified that each field in the hosted feature layer view should be editable by following the directions here,
If i select the option (in the AGOL Overview tab) to add the layer to a map with full editing control, i can indeed make edits. Adding the view to an existing web map is a no-go for editing
