Please TP-LINK, indulge with us that the voucher settings you are putting in place is not helping. i want to draw your attention to the voucher expiration date that makes our vouchers useless.

For instance, when i create 400 vouchers of 24hours validity, how can i use date for the expiration if i don't really know when they will all be used? we don't want unused vouchers to expire. we can delete them if we do not want them to be used; however we need an expiration time from first use, so our vouchers can be used anytime and be expired after a certain time. for instance, we can create a voucher of 5 hours, but assign an expiration time of 24hours from first use. in this case our vouchers stay without being worried about the expiration date if they are not used. please do something about it
