Stripe creates multiple customer ID's per email address

Hey everyone,

I’ve been looking into Greg’s Bubble x Stripe course, which is pretty great. One thing I’m not getting though, is why Stripe keeps creating new customers (meaning new customer ID’s), when there’s already a customer ID available for that email address.

What I mean is that upon check-out, the Bubble Stripe Check-out plugin sends the user email to Stripe Checkout. Rather than merge this with a previous customer ID with that email address, a new one is created. I can’t send along a customer ID with the Bubble Stripe plugin though.

Any solutions?
