The output layer created from an analysis tool in ArcGIS Online displays a size of 0 B from the item's details page.

Solución alternativa

If users are unable to wait a few days for the size to update, a potential workaround could be:

1. Select Export Data.
2. Export as a file geodatabase.
3. Once exported, select Publish on the file geodatabase screen. This publishes the layer as a hosted feature layer and displays the expected item size.
