I have created signatures and the look OK in Preferences but I cannot get them to be used. It worked once, but I am not sure how or why. I do not get all the dialogs.

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.

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 .
