I have a couple versions of a hosted feature layer that were created with two slightly different versions of a survey 123 form. Both hosted feature layers include attachments. I would like to merge these two hosted feature layers so I can create maps and dashboard elements using just one. I have attempted to append a zipped FGDB to the target layer and everything worked smoothly except the attachments do not appear to have made it. The FGDB took quite a while to upload, suggesting the attachments were uploaded, but I am not seeing them in the pop up via a web map like I do for the previously existing features. Any advice?
