Yes, I have the same issue when issuing a refund via Wallet. The system does not process the refund and hangs on screen. A refresh shows the refund has been issued but the wallet has not updated to reflect the refund and also the order status has not been changed to “Refunded” . This occurs when running the version 1.5.9/8 – I reverted to ver 1.5.7 and it is working correctly after the downgrade.

I have also tried tis across a number of sites with the same result.

WooCommerce version: 9.4.3
WordPress version: 6.7.1
PHP version: 8.3.14
