Chromium snap package was out of date

[Richmond]

Hi,

Although my system had been updated, both apt and the gnome software
updates reported it up to date, I found that chromium had not been
updated for 5 days and was out of date:

I updated it. But I read that snaps are supposed to be updated
automatically. How can I check that?

Chromium has a zero day in it, should be updated to 128.0.6613.84.
