dsThe Asynchronous Update allows you to execute SLA updates asynchronously after issue events.
We recommend only ticking this box if any field within the SLA's JQL condition might be updated during the workflow transitions. If you enable this option, then Time to SLA will make calculations after issue events occur. You might expect better issue load times, but there will be a delay of about one minute before seeing the changes on SLAs.
There may be times when Time to SLA has trouble keeping up with issue updates due to numerous automations. This could lead to problems with calculations and the wrong information being shown on the SLA Panel. Enabling the Asynchronous Update will get rid of such problems.
