Is Adobe Sign and Acrobat the same? Separate?

[JS Callanan]

Forgive the tone, but Adobe really has become the most convoluted, confusing software vendor - even toping Microsoft. A zillion products and horrendous communication. Case in point, I have a page (https://helpx.adobe.com/sign/kb/Avanced-Account-Sharing-feature-Adobe-Sign.html) that claims to explain how the "Enmable Advanced Account Sharing Feature - Adobe Sign" - yet what is displayed on the page is no where to be found in my account. I have a Create Cloud account with Acrobat Pro. I have accessed Adobe Siogn (I think) when using it, but despite a chat wioth support yesterday, I still have no clue where to locate and sort of setting for Adobe Sign, nor am I even certain Adobe Sign is an actual product, add-on - or just another name Adobe has slapped on something that is just part of Acrobat. Where is the documentation?

Yes, it's baffling at times, and regular changes of names, web pages, plans and everything else don't make it any clearer. Near as I can tell there is a limited version of Adobe Sign with Acrobat, but any fancy features need a separate subscription. But, since Google searches for Adobe Sign now take you to sell you Acrobat, that isn't much help. Near as I can tell Adobe Sign is now rebranded Adobe Acrobat Sign and they no longer push the high end products EXCEPT as enterprise solutions in a "contact us for details" category. E-signature Pricing and Plans | Acrobat Sign (adobe.com)
