I am having the a problem with 2 of my devices (iMac and MacBook Pro). I added the iMac first and a day later I added the MacBook. The MacBook doesn't show in Central, although changes I make on it (uninstalling the VPN etc) reflect in the dashboard as if i was doing the action on the iMac. It's almost like both devices are sharing the same device ID. I also installed it on a Windows 11 laptop, which registered itself just fine, as did my iPhone.
As a network engineer, im very familiar with MAC Addresses and based on another post I found having similar issues, checked both devices that seems to be sharing some form of ID and confirmed they had different unique MAC Addresses (on both Wifi and LAN interfaces) and none of the interfaces were virtual.
Seems to be a pretty big issue this does, and lots of people struggling with it. It's frustrating as on my MacBook it found an infected file (false positive) and it told me the file was actually on the iMac! I got very confused when I followed the file path, only to find the folder/directory didn't exist... no wonder, it was on a completely different computer than it was reporting it to be on!
I hope they sort this soon, as it's one of the reasons I invested in a 20 licence package, so i can add all devices for the family and manage them from a central dashboard... which it seems now I cannot until they fix it.
Are there any known workaround or fixes for this currently? It's driving me nuts.
