I think to make this actionable for staff, we should be very precise on what was wrong in the past and may work now, what has broken recently and suggestions for improvements (new feature requests). Please help make a concise list, below is just a start:
A Notifications
Defects: I know there has been issues in past but is any notification not firing at present?
Feature suggestions: Club admins don't receive a notifications, if their club is challenged to a Multi Club Arena, club members don't receive them for upcoming Multi Club Arenas. Question: "App users don't receive notifications for newly created forums and don't have an option to follow announcements, forums or match notes." Is this true? Did it break at some point?
B Club communication
Defects: Admin used to be routinly auto-muted by the spam filter and would have to contact staff to be un-muted. In my experience this is much rarer now and instead most often an admin is merely prevented from sending PMs for a few hours.
Now, you can still be auto-muted in open forums if you spell out certain words, say, "h*m* sapiens". This could be improved slightly though not at the expense of controlling legitimate spam and abuse.
C Multi Club Arenas
It appears some supporting features was never implemented. "Multi Club Arenas exist since more than two years now: Their code has never been completed and they still can't be used for club competitions." See OP (post #1) for details.
D Vote chess games
Feature suggestions: A widget on the player's home page should show each vote chess they are part of and whether it is his team's turn to move.
Feature suggestions: Solution for very fast vote chess (say 10 min per move) so players do not have to constantly refresh.
E Club redesign
Defects: discussed in a seperate forum https://www.chess.com/clubs/forum/view/known-problems-which-club-redesign-should-solve

I am also pleased some issues have been resolved and we have discussion of further enhancements.
I guess I don’t understand where the imagined new club redesign I had in my head which was going to help make my admin and club member role easier ended up such a nightmare and time waster. So please keep fixing things so we can at least have some thing workable like we had before.
