When we have a new user sign up, the wrong plan ID is being sent to Stripe. It's the id from an old plan we deleted, instead of the live plan we want. I can see the old plan in the wp_options table in serialized form, but not in the Pro Sites admin panel. How can I get the correct plan to pass to Stripe or get the old plans deleted and change customers to new plan? The pricing hasn't changed, we just needed to rename the plans. Thank you.
