When I go to Preferences, enable Live Notifications, Save Changes and then log out, that setting is not saved. When I log in again, Live Notifcations is disabled.
There is a note there that states
Note: You have to change this setting on every browser you use.
That might mean is not a separate cookie, but rather related to current session/browser. Once you log out and back in, that is simply taking a different ID, hence you have to enable it.
What? I’m using the same browser. I enable Notifications then log out. No Notifications? How useful is that?
I just explained to you.
Then it’s a mess.
Please wrote a mess report to the discourse developers and explain them that.
Closed, as the issue described here is not up to us to change in the functionality of the forum.
