Thanks for the response Mirko. I was able to replicate the problem tonight. I only have the WooCommerce PayPal Payments plugin activated.
More info…after billing details are provided and you click a payment method (PayPal, Venmo, or Debit or Credit Card), then the message appears. It’s only this product…unfortunately it is one of my client’s best sellers. We’ve recreated the product and that didn’t even work.
I did find if you add another item in the cart with the troublesome item, it seems to work. The whole thing is strange. If you have any other suggestions, please let me know. I will reach out to the other recommended forum.
