While editing in ArcGIS Pro, I began to get a schema lock and could not save. Shortly after, I received an error that the feature service no longer exists. I logged into AGOL to find that the hosted feature service had disappeared. The service definition and web map were still there.
I had to publish a new web map until I could figure out a cause.
Had anyone had to deal with this before? Any cause, or explanation from ESRI?
