How to change the symbology of on-premise feature services in ArcGIS Online

Following on from my post about "

how to add more functionality to your dynamic map services

", another common question Support receive is "

why can't the symbology for an on-premise Feature Service be changed?

" The symbology can be changed, but first you need to disable editing on your feature service by clicking the drop down arrow next to the service in the contents window in your map viewer:


Now editing has been disabled you can change the symbology of your features. This might be useful if you are wanting to symbolise a different feature attribute to the original template set up on the service. For example, you might have crime type feature templates set up when you publish your service but it might also be useful to symbolise the crimes by time of day.
