In rel. 11.2 of ArcGIS Enterprise, the bookmark widget of ExB doesn't allow to edit the spatial setting of the entry previously written but only the label. It'd be important to address the issue for future release.
Hi @mauriziobombace, Thanks for your feedback.
Could you clarify what do you mean of "edit the spatial setting of the entry "?
If you mean to edit the spatial setting of previous added bookmark, you can click the "map" icon to open spatial view editing window.
If you mean to edit the spatial setting of bookmarks read from web map, you are not allowed to.
The bookmark from web map is read only. You have to editing from map/scene view and the saved editing will reflect in ExB Bookmark
