2. Navigate to the Referral program section and slide the toggle to the left next to "Enable paid subscriber gifts".
What happens after I opt out of the gift subscription referral program?
Once you disable the referral program on your publication, future paid subscribers will not be able to refer new readers and current referrers won't be able to access the Gift Rewards page that allows them to send gift subscriptions.
