"Save & Complete Later" button not visible on iframe-embedded form??

My form is: https://form.jotform.com/201765631215147

It is embedded here (as an iframe): https://iynafit.com/ci/estee-dh7c5

How come I cannot see the "Save & Complete Later" button in the embedded form (though it is visible on the native form)?

As we check the web page, the form is embedded using the default Javascript embed method. Please try embedding the form using iframe embed code so that it should be working fine. You may get the iframe embed code for your JotForm by following the steps in the guide below:
