Seeing your client's signature on the document but the document status is still Viewed, not Completed?
The reason is likely that your client/signer hasn't clicked the "Finalize button" - hasn't completed the document.
To check that, you can go to your recipients list and look at the indicator next to the signer. If it says "Signer" in red, it means they haven't hit the Finalize button.
Please reach out to the recipient and ask them to click "Finalize". Once they do, the document will become Completed.
