I am currently working on a web map that will be used in the instant app attachment viewer. A map was created last year, and I want to use it as a backbone for my map this year, but replace the attachments. I tried saving the map from last year as a new file, and the layer I am editing the attachment of as a new layer all together by using "save as", but for some reason it is still overriding the original feature layer. This is a problem because the map from last year is still used and referred to, so I do not want anything on the original map to be updated. Is there something I'm missing? Thanks!
