Notifications arrive on their own
The bell updates the moment something happens — no refresh, and nothing lost while the tab was closed.

The bell
The bell in the marketplace bar tells you when a purchase goes through and when the studio has news to share. From today it updates by itself: a new notification appears the moment it's sent, without reloading the page.
Close the tab and you miss nothing — everything waits for you in Notifications until you come back.
Read means read
A notification is marked as read only when you say so: open it, tick it, or press Mark all as read. Having the tab open in the background doesn't count as reading.
