No Notification on Critical Software Updates

Wondering if I’m the only one (at least I have the same behavior on both of my F37 workstations):

It looks like gnome-software’s “critical upates are avialable” notification does not get displayed in Gnome. Or it looks like it tries to get a message displayed, but the pop-up is only shortly flashing, but doesn’t stay in the notification area. And it’s flashing so quick that you cannot see any text in it.

[chris@fedora ~]$ dnf updateinfo 
Last metadata expiration check: 0:02:43 ago on Sun 22 Jan 2023 09:17:55 PM CET.

The pending critical update is for firefox:

[chris@fedora ~]$ dnf updateinfo list|grep Crit
FEDORA-2023-ee8bfe7d72 Critical/Sec.  firefox-109.0-1.fc37.x86_64
FEDORA-2023-ee8bfe7d72 Critical/Sec.  firefox-langpacks-109.0-1.fc37.x86_64

And from dconf, I can see that gnome-software was indeed trying to notify me (update-notification-timestamp got updated each day since firefox update was available):

[chris@fedora ~]$ dconf dump /org/gnome/software/ | awk '/(check|up|in).*timestamp/ {print  strftime("%F %T", $NF) " " $0}' | sort
2022-11-21 18:18:16 upgrade-notification-timestamp=int64 1669051096
2023-01-10 08:26:00 online-updates-timestamp=int64 1673335560
2023-01-10 08:28:28 install-timestamp=int64 1673335708
2023-01-22 11:21:29 check-timestamp=int64 1674382889
2023-01-22 11:21:32 update-notification-timestamp=int64 1674382892

Version of gnome-software

[chris@fedora ~]$ rpm -q gnome-software
gnome-software-43.2-1.fc37.x86_64

Anyone noticing the same? There seems to be no bug report for gnome-software related to this. But maybe this is not gnome-software, but something else?

Update: today I refrained from touch anything and just sit there and wait. And, lo and behold, the popup appeared and stayed there for a while. It even still sits in the message center.

dconf dump:

[chris@fedora ~]$ dconf dump /org/gnome/software/ | awk '/(check|up|in).*timestamp/ {print  strftime("%F %T", $NF) " " $0}' | sort 
2022-11-21 18:18:16 upgrade-notification-timestamp=int64 1669051096
2023-01-10 08:26:00 online-updates-timestamp=int64 1673335560
2023-01-10 08:28:28 install-timestamp=int64 1673335708
2023-01-23 13:33:26 check-timestamp=int64 1674477206
2023-01-23 13:33:29 update-notification-timestamp=int64 1674477209

So maybe this issue is related to my workflow of hitting the Meta key (to get an overview of open programs) or a Meta-number combination (to start a program from the Dash) after wake up from suspend and unlocking the screen.
