After installing and activating the WooCommerce Extended Coupon Feature plugin the system generated coupon notifications that appear after applying a coupon code in the cart no longer remain on top of the shopping cart.
The coupon notifications are only briefly displayed and then immediately cleared from the shopping cart. There is no time to read the coupon notifications.
please try and purchase a ticket for 9 April 2017 ( https://tickets.universe.dk/billetkalender/ ) and apply the coupon code ‘sonderjyske’ at checkout. (PS. the coupon is not valid for that day!)
This will showcase the issue with the quick clearing of coupon notification messages.
