Check that your device's firmware is the latest version!

A service company that uses AyaNova was having a heck of a time figuring out why two different devices, an iPAD first generation and a Samsung Galaxy Note, were having the following issue:

[li] When attempt to sign on the signature window, the whole window that showed the signature box itself would move and not “allow” a signature to be taken.
[/li] [li] There was no message about incompatibility with the mobile browser being used.

This service company performed great troubleshooting - they determined that the firmware of the iPAD first generation was out of date and updated. And that resolved the issue for the iPAD first generation and now it can sign correctly.
