They might just not have cut a new build yet, today. It 'works' on master, but the mobile app thinks that your build is outdated (v0.0.0) if you build from master without overriding version, so probably easiest to wait until they cut a build if they haven't.
Woah, hadn't seen this before!
Off-topic, how long compile times do people have for codex-rs in openai/codex? Even my very beefy computer takes like 30 minutes to compile in release mode, makes me wonder why it's so slow and how this TUI got so large. But then I remember, agents like to write a lot of code, compilers get slower when they have to compile a lot of code :)
In my experience, although the build is a little slow, it's that LTO step that takes a million years.
