Not sure if it had the same issue as Accounts.onLogin not firing on client side:
However, I had noticed my Accounts.onLogin handler does not get fired on Chrome unless I actually login. So if I press refresh, the handler does not get invoked. On Firefox, the handler gets invoked even on a refresh.
That being said, how do we make it such that it works the same way on both browsers, what I’d like to do is set some default values on the session onLogin.
