Those are just the issues I can remember off the top of my head, but there have been many more. Both flatpak and snap feel shockingly half-baked, more akin to a tech demo with some fancy tooling than a battle-tested piece of foundational infrastructure.

Sure, maybe a lot of this is the fault of the apps themselves not having been built with containerisation in mind: but wherever the fault lies, it's still a rough experience for users.
