Correction,
That Create button is a result of having the wrong Theme selected for the mobile/tablet user.
The issue is when you start a ENTER NEW process and all the buttons on the form are disabled (I only want to use a custom HTML button to save form located in a HTML cell), the system still displays the [system's] Create button at the bottom of the mobile/tablet screen.
If the 'allow user to cancel process' is ticked, then the Cancel button appears as well.
I do not want to have these buttons displayed on mobiles/tablets if I've disabled them on the form.
Cheers.
