Not only it's inefficient, but (at least in Arch) it doesn't auto update on big versions. And instead of just warning you, it refuses to start until you manually install the new update. And god forbid if the package mantainers need a day or two to update the package, because until then you can't use it.

The funniest thing is, there's a file in the app's directory called "build_info.json" which contains the version number, and with a simple edit you can make it think it's updated, and it suddenly works without problem.

I really don't know what they're updating, but I have a version from 2021 running on my phone (it's old and the new app is really slow), and it still works fine. Even after the account handle change and several other additions to the app.

Oh, and for the Arch users: there's a discord version on the AUR called "discord-canary-electron-bin" that uses system wide electron, so it should be updated faster than discord's own bundled electron. I don't know if there's a non canary version of it, tho.
