I was using the S2member Stripe Pro Billing Modification Form so that when my lower level users paid a subscription it would trigger their level upgrade.
I’ve now moved on to using Stripe Connect with a Destination Charge so I can split the subscription with a referrer.
But how do I now trigger the s2member level upgrade when I’m not using the Stripe Pro form?
Is there coding I can append to the Stripe Connect payment to trigger the member’s upgrade?
Or is there an attribute I can append to the Stripe Pro form to link to the Stripe Connect payment?
