IOS app missing the ability to "Fill & Sign : Sign anything you've been sent" – Adobe Acrobat Sign Review

IOS app missing the ability to "Fill & Sign : Sign anything you've been sent" that is found in the Adobe Sign cloud app out on the web. You can send docs for other people to sign but you can't sign documents sent to you for signing. Lacking this functionality - I have to log into web site on mobile browser. What a waste.
