I have a hosted layer in ArcGIS on-line that I'm using in a map
I'm trying to update this layer having created some additional examples in ArcMap. As far as I can tell the data I'm adding is in an identical format; the field names match; the types are the same. But when I attempt to append I get an error saying - There was an error appending the uploaded data to the layer . There's no further information showing what's wrong and I'm stumped.
Any suggestions would be most welcome.
