Change device names when two share the same name

[kiwichick888]

I had two Android TV devices that had the same device name and I've given them to family members to use. When the first device connected to Jellyfin, I changed the name in Dashboard > Devices to something more relevant to where it is now. When the second device connected to Jellyfin a few weeks later, I changed the name of that one, too. However, changing the second device name also changed the name of the first device (presumably because they both had the same original name) and now they both have the same name again. Does anyone know if I can separate the two and, if so, how to do it? Eg: by MAC Address.
