The notification centre helps you manage developments in your portfolio, actions you need to take concerning new investments you are making, and updates in businesses that you may be interested in.
You will be alerted to how many unread notifications you have in your feed, and can view them by hovering over the notification icon. Should you need to pay for an investment or confirm a sale of a sharelot on the secondary market for example, you'll be able to take action on a specific notification right from the notification itself.
