Coupon Max Limit Usage and Subscription Problem

Hi there

I hope you are well.

I am using the Coupon plugin add-ons. I create two coupons one is Monthly and the second is Yearly. When I try to use the Monthly coupon on the yearly subscription it’s throwing an error and it’s correct but when I use the Yearly coupon on the Monthly subscription it’s applied but does not deduct the price and it’s wrong. Yearly coupons should not be applied to Monthly Subscriptions. Also, I create another Coupon with a max usage limit is one and I can still use this coupon more than one time with different accounts

Thanks
