Autotask PSA Integration: Devices Not Syncing To PSA

Is the site the device in mapped successfully? Device sync relies on site mapping
Does the device card show "open in PSA"? If Clicked where does it go?
Is the device one of the device types that are configured to sync in the integration setup?
Search the device ID in Kibana – any sync errors?
If in Kibana you see a "skipping sync – info hasn't changed", try hitting "force sync" next to the PSA ID on the summary card, or "sync devices now" in old UI and checking again
If still no sync attempt, make a small change to the device description (like adding a period or underscore at the end) and try hitting "sync devices now"/"force sync" again
If Kibana shows a sync error, does it reference any invalid IDs or elements in PSA? - Check those elements in their PSA account via PSA provisioning. A lot of device sync failures are a result of attempting to create the device in PSA and set fields to a certain value and that value was deleted or is inactive (configuration item type, product type, in some cases contact, etc.)
If device is synced to the wrong Configuration Item / Asset in PSA, you can use the new manually map options next to the PSA ID field on the summary card to sync to a different device
