Hi @obtrectation I’ve had the same issue with my client that uses this plugin. I’m 99% sure it has to do with the formatting of the credit card expiry field inputted during checkout. You can tell from the error message in the failed attempt. Most users will get it right after a few tries, and some have no issue, but I do believe this is the problem.
I’ve done a fair bit of testing, and the form validation/formatting of that field is a bit tricky. You have to match the placeholder example MM/YY in terms of format, which isn’t always that intuitive to customers. A lot of websites break this out into two separate inputs (month and year) to help improve the customer’s UX.
I’m about to work on a custom solution and will post it here once I finish. However, any updates from the plugin developers would be much appreciated.
Sincerely,
Blaine H.
