So sorry for the trouble @Anthony_Lozano,
I would recommend reaching out to our support team, so they can investigate this in more details. I would also advise you to provide them with the following details to help seeping up investigations:
- The URL of this conversation to provide our support team with some context
- The URL your attachement was attached to
- If possible, a copy of your PDF
Apologies for not being able to help you further via the Forum Anthony; if there is anything else I can help with, please let me know!
