Additional Information

The field alias stays because the pop-up saved in the web map uses the field alias "Change_this". The pop-up is automatically created when adding a feature service to the map. Because the field alias can be changed to anything desired by the user when creating a pop-up, it is not recommended to change the alias saved on the pop-up automatically. Remove the pop-up before saving the map. When opening the saved web map and add the pop-ups back, the alias is updated.

Workaround

Remove the feature layer from the web map then re-add the layer to the same web map and the field name is changed.This is not the best workaround as pop-ups and styles must be reconfigured.
