I added a public available web mapping service to my Organisation Portal. Since originally adding the owner has added 4 more layers to the service. How can I update my Map Image Layer to include these new layers. I can't find any refresh option and can only think I need to remove and re-add this which would take considerable time to reset the various pop-ups etc I have setup.
If it helps, this was my original process
Add the following map server to a webmap
On a side note, by doing the above process, will the general underlying data be updated as the owner updates or have I effectively taken a 'snapshot' of the data at the time I save?
