Have been receiving email from PayPal that IPN is not working. One off donations were updated but not recurring payments. I am on CiviCRM 5.16.4
How can I fix it please?
I have tried this but still not working anyone getting "IPN warning" emails from PayPal?
EDIT: Content of the email, also added a screenshot of the paypal IPN screen
