Hi,
There is nothing special with user points plugin configuration.
You can try it here:
This message contains confidential information
Checkout use default protostar template.
Now to reproduce the issue:
1. Add any product to cart and checkout
2.Login using credentials bellow or create new account, it doesn't matter...
This message contains confidential information
3. After successful login or registration you should see user points bellow payment method but user points view is not showing.
4. Refresh page and user points are showing bellow payment method.
Checkout config:
Thanks
