The hosted feature layers I've been testing have not been edited since April 2022, so I don't believe that's an issue here. I did some digging with a few of our hosted feature layers that have a considerable amount of attachments.  It seems like the "search" method on the Attachment Manager only returns whatever is the max record count for the service.  It doesn't seem to automatically paginate if the max record count is hit. Using the feature layer above as an example, I should expect a return of around 3GB in size for the attachments.  If I use the code below, only the first 2,000 attachments are returned...the max record count for the hosted feature layer service.  Even if I pass in a value of 9,999 for the "max_records" parameter used by the "search" method, only the first 2,000 attachments are returned.   import arcgis itemId = '...' # connect to portal p = arcgis.GIS('...') # set item object item = p.content.get(itemId) # get item layers layers = item.layers # set place holders attachmentSize = 0 attachmentCount = 0 # iterate over item layers for l in layers: # check if layer supports attachments attachmentSupport = l.properties.hasAttachments if attachmentSupport: attachments = l.attachments.search(where='1=1') # iterate over attachments for a in attachments: attachmentCount += 1 s = a.get('SIZE') attachmentSize += s # convert attachment size to MB attachmentSizeMB = ((float(attachmentSize) / 1024.0) / 1024.0) print(f'Attachment Count: {attachmentCount:,}') print(f'Attachment Size: {attachmentSize:,}') print(f'Attachment Size (MB): {attachmentSizeMB:,.2f}')     It seems that in order to retrieve ALL attachments you need to account for pagination/offset when using the Attachment Manager.  With the script below, which uses the "max_records" and "offset" parameters, I was able to finally return all attachments and get a similar number that the item page displays.   import arcgis itemId = '...' # connect to portal p = arcgis.GIS('...') # set item object item = p.content.get(itemId) # get item layers layers = item.layers # set place holders attachmentLoops = 0 attachmentSize = 0 attachmentCount = 0 # iterate over item layers for l in layers: # check if layer supports attachments attachmentSupport = l.properties.hasAttachments if attachmentSupport: # set query values attachmentMax = 1000 attachmentOffset = 0 continueQuery = True # get attachments while continueQuery: attachmentLoops += 1 attachments = l.attachments.search(where='1=1', max_records=attachmentMax, offset=attachmentOffset) # check for attachments if attachments: # increment offset attachmentOffset += attachmentMax # iterate over attachments for a in attachments: attachmentCount += 1 s = a.get('SIZE') attachmentSize += s else: continueQuery = False # convert attachment size to MB attachmentSizeMB = ((float(attachmentSize) / 1024.0) / 1024.0) # check attachment loops if attachmentLoops == 0: attachmentLoops = 0 else: attachmentLoops = attachmentLoops - 1 print(f'Number of Loops: {attachmentLoops:,}') print(f'Attachment Count: {attachmentCount:,}') print(f'Attachment Size: {attachmentSize:,}') print(f'Attachment Size (MB): {attachmentSizeMB:,.2f}')     ...
