So here’s a little bit of back story for you.
Originally, we had Express Checkout integrated with static buttons and fewer options than are available now.
A while back we added the Smart Button functionality, which you’ll see at the bottom of the Express Checkout settings. You can enable this to get nicer looking buttons in general throughout the site, and they have better functionality for Guest Checkout built into them as well.
When we first added Smart Buttons, we did not have them included in the regular list of gateways on the Woo checkout page. This is what changed in 1.5.5. We now have Smart Buttons fully integrated in all button display locations (if you have Smart Buttons enabled in the settings.)
You’ll see that you can adjust the size and some other options for those buttons, so you might be able to get it looking the way you like on the checkout page.
I do see that we lost the icons. We’ll get that fixed in another update coming soon.
All of that said, one of the primary benefits of Express Checkout in general is that users don’t have to fill out your checkout form. I would highly recommend that you enable PayPal buttons on product pages and the cart page if you have not already done so. By doing this, most people will skip the checkout page entirely.
If you want to try disabling the Smart Buttons altogether you can do that, too, and you may like it. I think you’ll find the smart buttons are better overall.
Let me know if you have any questions or concerns about that. Thanks!
