I think that is the issue. When you reset the computer, it gets a new name and there is a name conflict in the servers.
For instance, my computer was named "Asus_G14" after the reset but it shows "Asus-ROG-G14" under Settings/Account/Linked devices. It is a previous name that I used.
My computer gets listed randomly under devices when I refresh the web browser (or when I click on different tabs) then disappears again.
What you say makes sense, but I have 3 devices in my house with different names. Even though I enter my Microsoft account on another new device, why doesn't the device appear in the devices section? As a result, each device has a different name.
