The feature which allowed me to add a watch face to a collection was great… but it doesn’t work anymore. When I click the + nothing happens. Incidentally, although it is not as important to me, at the same time the web never updates the watch face I’m wearing anymore either.

Yes, something is definitely broken. A couple of us reported it over the weekend. 
Hi there - thanks for the report and sorry about that. We’ll try and get that fixed today!
