Does a vanilla Magento 2 store even use Paypal IPN?

I have a website using Magento 2.4

PayPal are losing their minds emailing me with the IPN notifcation failure e-mail:

“Please check your server that handles PayPal Instant Payment Notification(IPN). IPNs sent to the following URL(s) are failing: If you do not recognize this URL, you may be using a service provider that is using IPN on your behalf. Please contact your service provider with the above information. If this problem continues, IPNs may be disabled for your account.”

The thing is, PayPal is working perfectly fine — customers place order, I click Authorise, boom all done and dusted.

Is vanilla out-of-the-box Magento 2 even using IPNs? Can I ignore this email?
