Why is the PayPal Payment button not visible on some browsers?

A client from Hong Kong was unable to use our payment form:

He said that the PayPal Checkout button was not visible, and there was no other "Submit" button - screen shot attached

I have gone ahead and added "Submit" button in your form. Please test your form again and see if you are able to see the submit button in embedded form.

Do get back to us if the issue persists.
