Why isn't auto-sync (or auto-push) running right now?

Most likely you're outside your Active hours — whenever that's the case the sidebar shows "resumes 08:00" (or "resumes Mon 08:00") instead of a countdown, so you can always see why it's quiet. The moment the window opens, Relay catches up with a sync straight away rather than waiting out a full interval. If it says "paused — no days selected", every day chip in the Active hours card is off — select at least one.
