Hi @sesherwin !
It is not possible to affirm what is happening just from your description, but it’s most likely that your PDF reader is not able to validate at least one digital signature/time stamp added to the document.
Whenever you sign a document with Docusign, the platform automatically inserts a timestamp certificate, protecting the PDF against edits and ensuring that nothing has been modified since then.
As a suggestion, try updating your PDF reader's list of trusted certificates, it is usually available in the settings menu. If you use Adobe Reader, for example, try searching for AATL and EUTL.
If the problem persists, try downloading another PDF reader from the market. If you prefer, the Docusign support team can help you with any questions about this process.
