That's not a _problem_ caused by Let's Encrypt, as the intermediate certificate could have changed any time due to a major incident. It's bad practice to hardcode an intermediate certificate.

That's not possible.

That's bad design on the app designers part.

As stated in [the thread in the API announcement section](https://community.letsencrypt.org/t/beginning-issuance-from-r3/139018):

If you have adhered to the [Let's Encrypt recommendation of renewing 30 days _before_ the end of the lifetime of the certificate](https://letsencrypt.org/docs/faq/#what-is-the-lifetime-for-let-s-encrypt-certificates-for-how-long-are-they-valid), you should be able to put back the previous certificate and you'll have 30 days to fix your app until the certificate expires.
