How to exempt / change after a payment has been sent out?
This is an example from an UK club where the currency is set to be in pounds, but you would get your local currency.
To exempt or change the price of a member from a payment, you must go to the payment request and scroll down to recipients. Here you can go to the member in question and click edit
After pressing edit, you can uncheck the product to exempt or change the price. You can also exempt for individual products.
When you save, the payment request will be automatically adjusted in the member's Spond app, or they will receive a new email.
