The March 2020 reference sounds like a CA certificate.

 

You aren't just picking the first certificate in the list, as most browsers show this as the chain of trust

 

CA -> Intermediate -> Client Certificate

 

And they all have to be in date, and otherwise valid. So you have to check expiry date on the last one (you can usually trust the CAs to keep theirs valid).
