I recently moved from SDE to Hosted Feature Layers in ArcGIS Online. I have a field in one of my layers that is not editable. I'm not sure how this happened. It is nullable but I can't delete the content because on ArcGIS Online it says the field is not editable. Any idea how to change this? I would just reload the SDE layer but I have done a ton of edits and didn't realize this was an issue until now.
