I have a web map that uses secured services that are published on my server, but registered with AGOL. When I load that map in Operations Dashboard, it displays fine - but if I try to select a layer from the map, the layer list for that map churns indefinitely and never populates.
As a workaround, I have to use the "Select Layer" to pick one of the underlying services first, then choose a layer from that service. Even that is problematic, though, as my map service contains over a dozen layers, and there is not a scroll bar enabling me to scroll to layers or tables at the bottom of the list. I have to decrease the browser zoom or move to a larger monitor to see additional layers.
Are there any known limitations, such as problems with secured services or # of layers in underlying maps, that might be causing my main problem, and are there any plans to add a scroll bar to make the workaround a little easier?
