Well, as if life wasn't complicated enough, now we have to renew our Covid Certs after six months from vaccination/recovery to keep it up to date! Another date to put in the diary.

From Safe Communities, on Facebook -
EU COVID VACCINATION CERTIFICATES MUST BE RENEWED EVERY SIX MONTHS
If your 2nd dose of the vaccine was more than six months ago, it is time to ask for the renewal of your vaccination certificate in the available places: the SNS portal 24, the APP SNS24 or at one of the 750 counters Espaços do Cidadão that exist in mainland Portugal. The steps to renew it are the same as for the original.
The new certificate will have exactly the same validity period of 180 days.
Recovery certificates also have a deadline, only those who certify that the holder has recovered from an infection after a TAAN test performed more than 11 days ago and less than 180 days are accepted.

I'm going to use the 'W' word in Portugal

Why?

What happens after 6 months that makes the certificate need renewing?

Any stabs at that?

The certificate I get when I tap the button in the SNS 24 app neither has a date of issue or an expiry date on it. How can this possibly expire?

Well, in the comments on the Facebook entry some info comes to light - it seems to relate to the QR going out of date, or at least needing renewing to be valid (it was said that a lot of admin type things in PT have a life of 6 months so perhaps that is why???). There is some confusion too in the relevant date as some people only applied for the Certificate WELL after their date of final vaccination but it appears that the vaccination date is the relevant date here, so it may all need some clarification as yet.
Clear as mud in effect ...
