I have an issue saving my map (just a collection of points and a basemap).. I created it last month and I could modify it without any problem since last week.. Now, when I try to open the map, ArcGIS online says there are unsaved changes (?) and, if I open the map and try to save changes, the popup "saving" appears but nothing happens..
Anybody knows why? What I did wrong?
Thank you in advance,
