Sign using a certificate previosuly created, I cannot set the default signing method.

Hi there

I used to sign the documents using a certificate created in Adobe.

Now we have the Adobe Standard DC, and I can add my certificate, I can create the aspect of the signature, but I cannot set the default signing method.

So when I try to sing the document, I can only write my name or so on instead of place the signature as before.

How do I have to proceeed to sign with a Certificate as before?

Thanks
