I am using WooCommerce OPPCw payment plugin.
It does not require transitions to external resources.
The payment form is located on the website page.
After we get to the page for entering payment data in the postmeta database table for the coupon, the two values ??of:
_maybe_used_by_
_coupon_held_
There is a timestamp at the end of these values (Example: _maybe_used_by_9999 etc. )
But the payment has not been completed yet.
Why set a limitation of use if the purchase is not over yet?
