I have a form that asks users to upload several images and to provide a signature.
Several of the media files are missing from the media .zip download, despite the filenames being referenced in the associated field of the xls download.
It is similar to the issue described here: Missing media from .zip download - it doesn’t appear to be a problem with the size of the files, as the majority of missing images are signatures, so only KBs in size.
Forms were completed via browser. Most submissions were gathered without internet connection and uploaded some hours later once a connection had been reestablished.
Any ideas what could be causing the issue? Are the images recoverable?
