I am logged in to my account on 2 devices, and a saved mix does not appear on the 2nd device

There is something misleading about the state of a mix, and how it relates to an authenticated session. I logged in to the same Google account on a 2nd computer, and don’t see the “saved” mix on the logged in session on the first one. Either the mix isn’t actually saving. or there is something messed up with auth. The state should be in realtime, i.e., if I save a mix while logged in on one device, it should appear on the other device. I tried refreshing of course, and even that didn’t work, but a reactve SPA should propagate this change right away.
