I have added a web map from my ArcGIS Online organization account to an ArcGIS Maps for SharePoint web part. I am in edit mode and save the edit but when I refresh the page the web map I added is gone. I don't get any error messages saying the edit didn't save. The web part acts like it is read only. Might there be a configuration or permission setting that I am missing that needs to be turned on allowing me to make the edit and have it save?
