Why was my message dropped?

Messages are dropped when they exceed a rate limit — either your device published faster than the per-device interval, or your devices together exceeded the aggregate tenant rate. See understanding rate limits for the exact behavior and your plan's numbers.

Fix options: slow the publish rate, batch readings, or upgrade your plan.
