In addition to the information being passed on, there are some quick fix notes for Android users:
If you are experiencing an issue where you are zoomed in to close on the document to see the signature boxes (i.e., the e-sign button is missing), you'll want to Zoom out using the Android touch interface and/or use Chrome browser (which has been tested and works with Echosign)
If you have Auto-Rotate disabled, and you encounter a form field, the page will tell you to rotate, and then you'll be frozen to that view because auto-rotate is disabled. To correct this issue you'll need to enable auto-rotate on your phone (which is typically a default setting on most newer android devices).
Thanks!
