Very sorry for the delay getting back on this. Somehow I didn’t see it come through, but I saw your review so I came here to check it.
The only reason it wouldn’t show up is if you did not have the “Force Secure Checkout” option enabled in the WooCommerce checkout settings. Of course, to enable that you’ll need an SSL certificate on your site.
As long as you do have an SSL, though, and you have that option enabled the payment option should show up just fine on the front-end. Without those options enabled, you should have seen a warning message displayed that was notifying you of this in your WP admin panel. Over 20k downloads and I haven’t had anybody with any issues on that.
I see you already purchased something else, which is a bummer. Sorry again for the delay getting back with you. If there’s anything I can do to persuade you to adjust your rating please let me know!
