Woocommerce Square CC not loading for anon

I’m facing a nearly identical issue to this user here: https://wordpress.org/support/topic/first-payment-attempt-fails-everytime/

To reproduce:

1. Place any item in your cart
2. Go through the checkout flow, select either pick-up or delivery
3. Fill out all required fields
4. Observe: how the Gift Card field, has a “Enter your gift card number” tooltop on click, and Credit card number does not
5. Observe: Filling out the Card number field (when working/connected) will mask to the appropriate CC processor. 41… VISA | 34… AMEX
6. Fill out Card number with placeholder card (4111 1111 1111 1111 – 11/26 – 111)
7. Click place holder, and wait for page to reload
8. Observe: how the Card number now produces a tooltip below
9. Observe: how the card masking now work
10. Observe: how the Card goes through far enough to tell you it’s an invalid card

Context:

I’ve done my best to rule out caching, by disabling litespeed and siteground caching modules. We’re not using Cloudflare or any other external CDN.

This issue appears to be limited to anonymous users who do not yet have data in the session. I see a 304 request come in from https://web.squarecdn.com/1.83.4/single-card-element-iframe.html, from square.js as a logged in user, that I don’t see an anonymous.
