1. On the home screen fresh after installing. Click on Adobe ID login.
2. The screen name that appears after clicking login is "Close".

I'm unable to attach an image in my device. The only attachment options available are camera, camcorder and uploading PDFs. It will be good to add the option for users to share screenshot. If you need more information please contact me. I will share the details.
