How to verify that my URLs are valid and can be converted to attachments?The extension is adding my files. The icons start showing then they disappear immediately. They seem to get deleted after being uploaded.
Some URLs are being converted to attachments but not all.Some records even have the same exact link.
Error "preview for this filetype are not available"
I have multiple URLs in a field, but only one URL is being converted to an attachment.
The new attachment thumbnails are showing as gray icons.
