You asked for PayPal to be a payment option. Are you getting a lot of requests for this?
There are quite a lot of things Paypal can’t do in terms of subscriptions. It can’t handle multiple subscriptions, it doesn’t allow for changing the subscription amount, or the date or for subscribers to change their subscription.
I can easily switch it on but it might be best to have a think about whether it will be more trouble than it’s worth if it causes confusion with parents.
