In general, there are two reasons why a task might be delayed, or might not be appearing to run:

  1. Shopify† is delayed in sending notifications to Mechanic
  2. Your Mechanic account is experiencing a delay

If Shopify is delayed in sending notifications to Mechanic...

... then you won't see anything appearing in Mechanic's activity log, and you might see something reported on Shopify's status page.

In most cases, delays are resolved in time, and the delayed events are later on sent to Mechanic, where they can be processed.

A note about update events

So as to avoid sending out floods of notifications, Shopify waits a few seconds before sending notifications for update events, to see if any other updates occur that should be included in the notification.

For example, if you change a product's title, then save it, then notice a mistake and change the title again, Shopify may only send a single update instead of two. This means that update events take a little longer to arrive than other events.

If your Mechanic account is experiencing a delay...

... then you'll see a steady stream of incoming activity, in your account's activity log, but you might not see activity corresponding to the very latest events in your store. Mechanic has some currency limits that determine how much can happen in your account at once, and if you reach those limits, processing may be delayed until Mechanic catches up.

† This article's notes about Shopify apply to all event providers – any service responsible for sending an event to Mechanic.
