I do get the occasional missing messages in the desktop client but what I notice most is that it gets unstable and weird when there is a update available (which I don't get notified about). Desktop and laptop with Ubuntu btw, signal installed via snap if I recall correctly.

Have you checked if yours is up to date?

I have the PPA set up and it autoupdates, but I will double-check, thank you.

are you on matrix.org? could have been the issue - but they should appear at a later moment, though

Signal with matrix.org? Not that I know of.
