Permanent assignment is lost – affiliates permanent – woocommerce coupon exclusions

Dear Team!

We have been using the “Affiliates Permanent” plugin for a long time. Now some customers have entered a second voucher code from another affiliate partner – but this should be prevented. We have also used the “WooCommerce Coupon Exclusions” plugin so that certain voucher combinations cannot be entered.
Now it turns out that if a customer (A) is permanently deposited with an affiliate partner (A) enters a voucher from another affiliate partner (B), the permanent deposit of the customer (A) with affiliate partner (A) is lost and is lost to him Affilate partner (B) assigned – that shouldn’t be.

If a coupon (265427) is entered in the Remove coupons field in the “WooCommerce Coupon Exclusions” plugin, the coupon (265427) can still be entered in the shopping basket and will not be deleted.

How do we manage that a customer (A) who is permanently assigned to an affiliate partner (A) can no longer be automatically assigned to another affiliate partner.
It should also not be possible to prevent certain combinations of vouchers.

With the ask for support
