63103: Cannot assign payment method to WABA provided

The WhatsApp Business Account (WABA) provided is unable to use Twilio's credit line. Due to technical limitations within Meta's systems, once a payment method is added to a WABA it can only be revoked but never fully removed.

• Using a WABA currently assigned to another payment method
• Using a WABA that has been used with another provider

• Create a new WABA to use with Twilio
