Please have a look at this customer:
According to the history he bought a subscription with us on 19th August. But the webhook was fired today. This is a delay of 5 days which is totally unacceptable for an in app payment.
Please verify whether the buy date (19th Agust) is really true or an error
And if it is true, you have to make sure such delays won’t occur anymore. Such huge delays can make customers get really mad and make them want their money back.
