Hi. I have a hosted feature layer with a date/time attribute field published from ArcGIS Pro. In the ArcGIS Online web map, if I click to 'Enable Time Animation' on a layer, the features disappear from the map viewer. If I don't click on 'Enable Time Animation' on all layers, the web map app (created in web app builder) displays a message stating 'No time-aware layers are visible.' I don't understand why features disappear when I 'Enable Time Animation,' seems counter-intuitive. I can kind of understand why I see the other message in the web app map. Any help would be appreciated. Thank you in advance.
