Stripe Billing Method Field not working for customers

I’m receiving reports that appear to come mainly from PC users that the Billing Method credit card fields of s2Member form pages are grayed out and people are unable to enter their payment info and complete checkout.

I’m a Mac user and in all my browsers and devices it appears to work fine.

We are using s2Member Pro v191022 and WP 5.3.2.

For reference, errors have been reported on this page:

I’m on Linux and don’t see a problem with the Billing Method section with Firefox or Chromium either.

What browser were they using? And in the browser’s console, is there any JavaScript error mentioned?

Does it happen consistently for those users, or only sometimes?

I see the problem on my side on Mac Chrome Version 78.0.3904.108 (Official Build) (64-bit)

Javascript errors:

I still haven’t been able to reproduce the error but I’ve enlisted help and whether it works or doesn’t work seems independent of the browser and device, at least on the surface. I haven’t been able to get people to tell me which builds of the browser software, for the most part. We are still getting orders through in Stripe, but still plenty of people complaining they can’t place an order.

Thanks to CommonJuke for providing the error report. Is this something that I can correct on my end in the Wordpress admin, or does this require an update to the plug-in?
