I've got several feature layers in an existing base map that no longer load into an existing base map. I can pull each one up individually, and have even tried to save them as a new base map to begin anew. Each time, as long as I'm in the editing window where I first pulled the missing feature layer, it shows up just fine. As soon as I save, go out and come back into the web map, it will no longer load. Any suggestions? Most of these layers are shared with field crews through Collector / Field Maps / Survey 123 and have heard no issue from them. Problem appears in the base map where it is then used for Web Map Apps & Dashboards.
