Read and filter notifications
Filter the list
Section titled “Filter the list”On the notifications screen, the filter control toggles between all notifications and only unread. If the pending filter is active and the list is empty, it returns to Show all to see those you have already read.
Mark them as read
Section titled “Mark them as read”Select a notification to mark it as read and, when the type allows, go to the related content. There is also the action Mark all as read if you have pending notifications.
Marking them as read changes the read status, but does not delete the entry from the list.
