I would like to know what are the limitations in ArcGIS Online web maps compared to ArcGIS Desktop maps(MXD) or ArcGIS Server map services. Some limitations which come across to me are the following -
1. ArcGIS Online web maps don't support group layers. We need to add individual layers?
2. There is limited support for symbology. Complex symbols cannot be set for point features?
I am not 100% sure of these limitations, these may not be limitations currently. Are these still valid? Are there any more limitations in terms of web maps in ArcGIS Online?
