Hi @Steve_1
The older client area has been discontinued. The new one was introduced back in 2018. Due to on-going updates, this area has now been enabled for all accounts.
You can add a link the statement by going to Account Settings >> Design Customisation, and select Client Area Customisation. Just tick the “Include horizontal menu system”, and this should come with a statement option as standard.
You can also add additional items on the menu here, if you wish.
Hope this helps!
