I received a failed charge email. What should I do?

If PayPal cannot charge you for some reason, we receive a cancellation request on your PayPal subscription. This can make your package automatically terminated on the due date.

Of course you can wait till it terminates to resubscribe, but is it really that necessary?

You don’t really have to wait for it to terminate. If you receive a failed charge email, you can simply login to your package and update the payment details as per the screenshot.
