Just downloaded the app. This is exactly the same as the web version. Literally the exact same. you even have a link to “get the app“ IN the ******* app. The login is just as onerous as the web version and the navigation is awful.
The Acrobat Web app https://documentcloud.adobe.com in mobile browser redirects you to download the Adobe Sign mobile app in certain flow. We will look into improving the experience.
In the meantime, you can use Request Signatures within Acrobat Web on tablet or desktop browser.
Thank you for your feedback.
