Update - Another issue currently affecting the Nylas Dashboard is some accounts (usually newly added ones) fail to show up in the Dashboard, or show up after some delay. We're continuing to work on systemic fixes for our Heartbeat service as well as making sure all syncing accounts show up quickly.

Update - The account statuses on the new Nylas Developer Dashboard rely on a new and experimental Heartbeat service. Our engineers have been continuing to diagnose systematic fixes to make that system a more accurate reflection of the actual underlying sync status. Until we can guarantee that the new Heartbeat service reliably lines (and ideally exceeds) our old reporting mechanisms, there may be inconsistencies in the statuses being displayed by the new Nylas Developer Dashboard.

Identified - The list of account statuses is currently misleading on the new Nylas Developer Dashboard only (https://dashboard.nylas.com). Many accounts are incorrectly marked "Stopped" when they are actually running. This is due to an ongoing error in our status reporting system.

The old Nylas Developer Dashboard (https://developer.nylas.com) has more accurate account statuses.

We have identified issues in the new service we're using to report stauses and are actively working on fixing this now.
