Am I correct in seeing a difference in lastSeen-propertie in the API versus the Last Activity in the Portal?
Of a specific Device:
Jul 25, 2024, 13:51:43 is the Last Activity in Portal
2024-07-25T09:28:01Z is the lastSeen in API

It is even not a difference rounded hours. So it looks as if Last Activity is something else than lastSeen.
Any ideas/comment?
