We recently made an improvement to the workflow email โOther Attachmentsโ feature that you may find valuable.
It is now easier to include a file created by the โSave Fileโ workflow action as an Other Attachment in a subsequent workflow email.
Previously, we only looked for Other Attachments under the worksheet folder. We recently enhanced Other Attachments to check both there and under the โDefault app folderโ. By looking under the โDefault app folderโ, we make it much easier to attach files created by the Save File workflow action.
You can now define a workflow rule with one or more Save File actions that create attachment files, and easily include them as Other Attachments in the subsequent workflow Email action.
For more information see topic โSpecifying Other Attachment in Your Applicationโ in this article https://help.appsheet.com/en/articles/3337387-email-other-attachments
I was just struggling with this the other day, awesome improvement!
