Tested launching AppImage with --no-sandbox and ELECTRON_DISABLE_SANDBOX=1
Notes
This appears to be a Linux-specific runtime / sandbox / Wayland issue where the Sync module fails to register its settings view, even though the core plugin toggle is present.
This is not a UI misunderstanding — the Sync settings page is completely missing.

Community plugins: for bugs, please first try updating all your plugins to latest. If still not fixed, please try to make the issue happen in the Sandbox Vault or disable community plugins.
I didn’t realise that I needed to make a new remote vault, I thought I was supposed to make my existing vault into a remote.
I can’t remember where I got the idea that the Sync button should be under Options. It could have been ChatGPT! I didn’t read the docs thoroughly as I thought something was wrong with my Obsidian install.
Anyway, I’ve made a new remote and sync works fine.
