Defender Endpoint device not sending device update

Question

I onboarded a couple of devices to Microsoft Defender and some do not send device updates. This one for example has been online in the past three days, the Device Last Seen also confirms this ("Jan 10, 2022 6:44:20 AM"), but the last update is still 7 days ago. How do I troubleshoot that?
