Fill and Sign signature repeatedly disappears

Repeatedly for numerous people in our firm, their signature in the Fill & Sign tool disappears without them removing it. Thankfully, it is saved as a png that can be simply readded, but this has happened over 5 times to one user in the past week. Any ideas why this is happening and what I can do?

    Hi Lisa35511437kpa1,

     

    Thank you for reaching out, and sorry to hear about your experience.

     

    Signatures are stored locally, and corruption here can cause both disappearance and upload errors. Please try the following steps:

    • Close Acrobat completely
    • Navigate to: C:\Users\<YourUserName>\AppData\Roaming\Adobe\Acrobat\<version>\Security
    • Locate and rename the file: signatures.db → signatures_old.db
    • Relaunch Acrobat and try creating/uploading a signature again.

    Try to reset the application preferences: 

    • Rename the Acrobat preferences folder: C:\Users\<User>\AppData\Roaming\Adobe\Acrobat\<version>

    Reboot the machine once after these steps.

     

    Let us know how it goes.

     

    Thanks,

    Meenakshi

    Hi, despite all the replies that say we need to click save signature, I can assure you that I AM clicking save signature. It will use my signature for a few sessions, and then disappear. Sometimes if I open 2 or 3 PDFs to sign together, it will work for 1 or 2 and then disappear. 

    I’ve tried logging out and back in, but I just have to go through all the hassle to make another signature. Then I have PDFs where my signatures look quite different because trying to get a consistent signature on a touchpad or phone screen is not easy.

    Hi Michael309314131m8g,


    Thank you for reaching out,  and sorry to hear that you are experiencing issues.

    To help us investigate this behavior further, please provide the following information:


    • A short video demonstrating the steps you are taking to add the signatures and what happens when you try to sign the PDFs.

    • Since when have you been experiencing this behaviour?

    • The complete version number of Acrobat you are using.

    • The operating system on your machine.

    Once we have this information, we can further assess the problem.

    We look forward to your response.


    Thanks,

    Meenakshi

    Hello - I also believe that the save signature box is not the issue here. Thank you to ​@Lisa35511437kpa1 for responding and thank you for the steps you gave her, I will try them as well. 

     

    Do you know if it matters at all that when I am adding the signature, I am adding it from a network drive? Would that cause additional corruption, and it might disappear less if it was stored on the C drive?

    I have also experienced disappearing signatures in the Fill & Sign tool, and it is NOT an issue regarding to failing to “Save Signature”. Additionally, when I try and upload a new signature, I get an “unknown error” message preventing me from uploading any signature and using the feature at all.

    I have tried restarting the Adobe, restarting the computer, changing the language in preferances, etc. and nothing has worked.

    This happened a few weeks ago, and the signature magically reappeared, and yet, here I am with a missing signnature again. 

    This has resulted in hours of wasted time trying to complete what should be a basic task, and the main reason I use (and pay for) Adobe.

      Hi jkaplan_fhassoc,

       

      Thank you for reaching out, and sorry for the delayed response.

       

      As mentioned, the signature disappears from the Fill & Sign tool without being removed. This typically occurs if you do not check the "Save Signature" box when you click on "Add Signature." Please ensure that you select the "Save Signature" option in the window that appears after clicking "Add Signature." For your reference, I've attached a screenshot below.

       

       

      For more information on adding a signature, refer to the following help document: https://adobe.ly/4cINBuS.

       

      Let us know if that helps or if you have any questions.

       

      Thanks,

      Meenakshi
