Seems like a pretty odd thing to leave out - signatures should have the option to be device specific, but not forced. The same signatures you have created on the desktop version of the application should be available for you to use on the mobile app. It's especially strange that there is not even a way to format your mobile signature - just plain text. The lack of options makes business emails sent from your mobile device discontinuous and less professional.
