How can we save the form on mobile devices to come back and complete

HI

Sometimes we get busy when filling in the form, is there a 'save' feature I can add so we can come back in and not lose all the info?

There are 2 different options to save your form as you go.

For long forms: How to Save Forms to Continue Later where forms data is saved on each page turn (when you switch pages)

For shorter pages: How to Enable Auto Fill Feature where forms data is saved after it is added to the same field.

Both will however allow you to save the entered data and continue at a later time, but since you mention that it is on a mobile device, I presume that you would be continuing it over the same device and as such the second option (Auto Fill) might work better for you.
