Contact list no longer available in new Teams version

This morning I have finally been strongarmed over to the new one with no option of going back, so in one massive backward clusterfrak (forced on me by people who seem to have no concept of real-world workflow) I can no longer see at a glance the online / offline status of my colleagues in the various departments (and beyond) who I interact with on a regular basis.

Formally, just in case anyone from Microsoft is reading this to gloat at the success of their latest attempts to completely eff things up, the "View Contacts" option is not a viable alternative as it's just an address book with no basic online functionality that a sane person would expect to see from a product that things it is the centre of the work environment.

Absolutely ludicrous... if completely in character.
