Prosites and Stripe Not Connecting

Our Prosites and Stripe still do not talk to each other. The webhook is successful, status 200, but the customer is NOT entered into the wp_pro_sites_stripe_customers or the wp_pro_sites_signup_stats tables, but is entered into the wp_pro_sites and wp_pro_sites_daily_stats tables. In Prosites Management it says: This site is using a different gateway so their information is not accessible.

Do you have any idea why the customer wouldn't be inserted into the customers table when the webhook was successful?

thank you.
