Tailscale logs me out if I log into a second user account on macOS

Early user of Tailscale and loving it. I happened to log into a second user account on macOS Monterey (simultaneously). I tried to connect to my Mac using the Files app iOS and it failed. I walked to my mac, and flipped back to the primary account and I was logged in. Tried to connect from iOS and it worked. I flipped back to the second account and iOS Tailscale connection failed again. Flipped back on the Mac to primary account and sure enough I was logged out again.

I tried to log into Tailscale on the second user account and it told me that I couldn’t because "someone else is using it).

Is this a bug or a feature?
