I can import it as an ordinary map layer just fine but I can't seem to import it as a feature layer as per title. I've played around with the formatting in the .csv and nothing seems to help, it won't even import a single line file. Google and esri help didn't have any info on the issue, so would appreciate any help.
Hello Russell,
Have you followed the steps mentioned in Publish features—ArcGIS Online Help | ArcGIS?
Yes I've followed the instructions for uploading, i have sufficient privileges, and my csv is formatted according to those requirements.
