I’m having the same issue that has been described above. Customers report that they cannot enter their credit card information into the form. I have seen the same behavior myself, but it has been intermittent.
I have followed the suggestion of changing the setInterval to 2000, but that is not a great experience. Please continue to look into this issue.
I am currently running v1.2.2 and the problem still exists. I will update with any other information that I can gather to help track this issue down.
