Certificate expiry notification (Proxy CA)

Hi

I received an email from my Sophos instance with the subject "[example.com][WARN-600] Certificate(s) will expire"

1 certificate(s) will expire within the next 30 days:
Proxy CA

–
System Uptime : 231 days 21 hours 19 minutes
System Load : 0.17
System Version : Sophos UTM 9.705-3

I know the issue is discussed both in this forum and the support KB. However, I do face a problem not addressed in these links.

In my Sophos

a) "web filtering" is not enabled


and b) the page "Web Protection > Filtering Options > HTTPS CAs" suggested in the KB is not "active", ie I cannot click or download any certificate


So my questions are:
1) I am going to be affected if this certificate expires?
2) How can I check if the certificate will auto-renew, since the page is inactive  and I cannot interact with it?

Regards

Vangelis
