I am not sure it is fixed.
There is a very odd (and what looks like a big security risk) situation in that it seems to switch you to a random account when you come back from the OAUTH dialog.
And fully logged onto that account as well, not just some sort of dummy account.
Tried this on a virtual tablet on Browser Stack and it logged me into another account. There can be no cookies on that machine whatsoever, so it isn’t an “old” login being picked up.
Ah, so what it appears to do is log you into the account that is already connected to that OAUTH account.
So you can’t connect two bubble accounts to the same OAUTHed account ?
