After updating One Step Checkout to 2.2.4, the checkout screen won't finish reloading when reward points are updated.
The Reward Points module version 1.0.6
Could you please check it?
The root of the issue is that the order summary is not updated after completing the ajax. So it causes the loading forever on the checkout page.
To fix it, we have changed this file app/code/Bss/RewardPoint/view/frontend/web/js/action/set_spendpoint.js
Please check and apply the attachment file on your site.
