Hi robertc70343455 ,
Would request you to Please refer to this article :- Digital IDs in Acrobat DC
If you have signed the document using 'Fill & Sign' tool, then open the file using sign option from Fill & sign you may sign the document , refer to this link :- Using Acrobat Reader DC Fill & Sign
Let me know how it goes .
Once you create the signature, click on tools, scroll down and click "Fill & Sign", select the file or document you want to sign, once doc opens, click on the "Sign" marker in the "Fill & Sign" toolbar and move your mouse to the location on the document and click your signature. You can also increase the size of your signature by hitting "Control +" or smaller by "Control -".
Good luck, I hope this helps.
Thank you. I read the article you cited, as well as others, several
times. Creation was no problem.
My problem is that the HELP never said, that I could find, the HELP or
HINT to search for a tool called Certificates. I searched,
Signatures, Digital Signatures, and many others but they lead no where.
I think the HELP needs some HELP.
