i used the application "Interactive Legend" and i can't see anymore the linear layer (with a categorized style) which is visible in the related Web Map. Until yesterday, it was visible in the Interactive Legend and i did not modify the application for months.
If i open the Web Map, the layer is normally visible on the map.
I don't know what's the problem.
Any suggestion? Maybe an issue of the last updating of the Arcgis Online?
Thanks a lot.
