I want to add a 3 new fields to a hosted table on ArcGIS Online. If I upload a new csv file that has 3 new fields to 'overwrite' the hosted table, the three new fields do not upload. The same thing happens if I do an append. I tried to add the fields directly to the hosted table online. The field will add, but when I upload the .csv (with all identical matching fields), the fields I added directly to the hosted table disappear. Is there a way to add fields to a hosted table without the fields disappearing?
