I have just renewed a certificate that is used for our web services and asymmetric encryption. I received the following bundle that I will need to provide to my clients, but two of the certificates in the chain are going to expire in May 2020. I've been told by the issuer that there will be no impact, but I'm not convinced as they didn't provide any details as to why there won't be any impact. Can you tell me what will happen on the client side when the root and intermediate certs expire, but my certificate has not? Please see the below image for a clearer picture of the situation.
