WooCommerce (funnelkit) Guest Payment Fix with Order-pay E-Mail Link

My store runs on the latest WooCommerce build with Funnelkit, yet the “order-pay” link still forces shoppers to log in before they can clear an outstanding order. Guest checkout is already enabled in the settings, so the link behavior, not the general checkout, seems to be the culprit.

I need someone who can dive into the templates, hooks or filters controlling that endpoint, identify why the session is demanding authentication, and modify it so customers can settle their order directly as guests. The final flow should:

• Open the order-pay page without a login requirement
• Pre-populate the outstanding total accurately
• Offer Credit/Debit Card (Square) and PayPal by default, with Apple Pay and Google Pay showing for supported browsers/devices
• Pass test transactions in both sandbox and live mode

Please work on a staging copy first, document the exact code or setting changes, and deliver a concise change log so I can re-apply the fix after future WooCommerce updates.
