Under ‘New’ or ‘Unread’ you may find that you have a number in brackets (43) (15) - that’s how many new or unread posts that you have waiting for you to read. If you want to clear those click ‘new’ and click ‘dismiss new’ to the right of the topped menu. Do the same for ‘unread’.
Also you can find ‘dismiss new’ button at the bottom of your ‘new’ or ‘unread’ posts. If you still cannot see it, email us at email@example.com.
