A push that half landed is worse than none
Changing a dish once and sending it to every kitchen is the point of a group menu. The hard part is what it says when only some of them took it.
If you run the same dish in several units, you want to change it once. Put the new price on the company's version of the burger and push it down to every kitchen that follows it. That is the whole point of a group menu, and it is the feature people buy a multi-site system for.
The sending is the easy half. The half that decides whether you can trust it is what happens when the push does not reach everything.
Half an estate on the new price is the bad outcome
Consider the two ways a push can fail. Either nothing lands — in which case the screen says so, you try again, and the only cost is a minute. Or some of it lands. Now eight kitchens are on the new price and four are on the old one, your screen said it pushed to twelve, and there is no way to tell which four from the outside. The next person to notice is a customer paying yesterday's price, or nobody at all.
So a push across an estate wants to be all or nothing. Ours sends every update in a single transaction now; before, it sent one at a time, which meant both that it was slow — a round trip per kitchen, in series, with somebody watching a spinner — and that it could stop half way with no record of where.
The rows that did not move are part of the answer
The other half of trusting a push is being told, every time, about the kitchens it deliberately skipped. A unit whose menu is held by the food hall it trades inside cannot be written to by the brand above it — that is correct, and it is also exactly the kind of thing that must never be quietly dropped from a success message. "Pushed to twelve" when three of them were blocked is a report that will be believed and is wrong.
Our push comes back with three counts: what changed, what was already matching, and what was blocked with the reason for each. None of that is clever. It is just the difference between a screen you can act on and a screen that makes you go and check twelve menus by hand.
If you are looking at group-menu features, the question to ask is not whether it can push. It is what it tells you about the ones it did not push to, and whether a failure half way leaves your estate in two states.
