When a document fails to upload to a Zylpha bundle, you'll see a red progress bar and exclamation mark against the document.
This can be caused by closing or refreshing the browser tab during upload, or other issues with internet connection.
If this occurs, you can attempt to re-upload the document by right-clicking and selectin "Upload".
If the upload continues to fail, we recommend using print to PDF on the document before attempting to re-upload. Guidance on using print to PDF can be found here.
