Issue with Apple Pay processing

Hi team,

I have a client website that is experiencing issues with Apple Pay not processing payments. The button sends the buyer to the Apple Pay payment screen. After they have verified their details they go back to the cart or checkout and the button sits in an endless loop and does not finish the transaction. This is occurring on both the latest version of the plugin, and the previous two versions. I’m trying to troubleshoot the cause. Nothing comes up the logs as an error.
