Contact Book - is it back? (again)

Is this back now for everyone?

I appear to have this, but it appeared as part of Echosistant so don’t know if that pushed it in to existence in my hub, and it’s still not working properly?

The main reason I ask is that if it has appeared then when using it I can’t have app notifications, which I believe require you to enter your email address… but clicking on the field brings up a numeric keypad and not a regular keyboard. (I’m using the iPhone app if relevant)

Support say no…
