Dark grey transparent screen appear when try to sign document

[Wozzar]

I've been sent documents to sign and am unable to. When I attempt to add a signature all I get is a dark grey transparent screen (so the doucment is still visible behind) with a white pixel in the middle of it. I presume this is also why the signature field is the only field inactive in the doc as I am unable to add one.

Hey Wozzar!

Thank you for reaching out and sorry for the trouble.

As you get the grey screen when trying to add a signature, please try the following steps:

1. In Acrobat, go to Edit > Preferences > Signatures.

2. Under Creation & Appearance, click on the More button.

3. Uncheck the box for "Use modern user interface for signing and Digital ID configuration".

Check if that helps.

If the issue still occurs, check if you can add signature on other documents.

Also, share the Acrobat and OS version details with us.

Let us know how it goes.

Thanks,

Meenakshi

Thank you Meenakshi. I gave that a try but to no avail. I have uninstalled and reinstalled Acrobat (which is a recently updated version) as well. The MacOS is Catalina 10.15.7. I haven't actually been able to save the pdf in its partially completed state either. I tried a new download of the pdf with the same result. The last time I was able to use my partner's Windows version of Acrobat to do the forms but I would love to be able to do it myself. 

Another thing of note, the signature section doesn't even seem active on mine but does when viewed on hers. 

Thank you again. Warren
