64b424a2aaThe hosted_fields_loaded listener referenced the bare PAYPAL global without checking whether it existed. PAYPAL is set asynchronously by the externally-loaded c.paypal.com/da/r/fb.js beacon script, which has no sequencing guarantee against hosted_fields_loaded firing (a load- order race, or fb.js being blocked by a content/privacy blocker), causing an uncaught ReferenceError on classic checkout with Advanced Card Processing enabled. Check window.PAYPAL (a safe property access returning undefined) instead of the bare identifier.
