Why Aren’t My Odoo Payment Extensions Appearing at Checkout?

If you're using custom or third-party Odoo payment extensions and they're not showing up during checkout, the issue may lie in one of several technical areas:
Configuration: Ensure the payment method is enabled for the correct website and country under Payment Acquirers.
Dependencies: Some Odoo payment methods require additional modules or configurations—check the logs for missing dependencies.
Version Compatibility: Confirm the extension supports your current Odoo version.
Access Rights: Check if the user role has permission to use the payment option.
