You could already close a date: the plan schedules no session on it. One click was still needed — “Regenerate the plan” — for the load to be redistributed across your remaining days. That click is no longer necessary: the proposal now arrives on its own.
What you see
A “A proposal is waiting for you” card, with the reason in plain words: “You closed Sunday 15 November. Here is the plan that takes it into account: the load of the coming weeks is redistributed across your available days.” The chart compares your current plan with the proposed one, week by week, and you choose which weeks you take.
The two buttons are the same as for any other proposal: “Take these N weeks” or “Keep mine”. The plan never changes unless you decide. That has been the principle from the start, and closing a day is no exception.
The card renders identically on the computer and on the phone. That was not free: until now the mobile app ignored any proposal whose reason was neither “you ran more than planned” nor “less than planned”. A proposal coming from a closed day would have been invisible there — waiting, without you being able to see it or decide on it, on the screen you hold on the trail.
What it does not do
Closing a day regenerates nothing by authority. MushMate computes a plan and shows it to you; it does not overwrite yours.
If a proposal was already waiting — because you ran more or less than planned — closing a day does not replace it: it is refreshed. The earlier one had been computed without your new constraint, so it answered a question that had become incomplete.
And if you had already accepted or refused a proposal, closing a new day opens another. That is deliberate: your gesture is a new fact, not the repetition of a gap that lingers.
A race does not move
As always: closing a date never moves a race or a milestone. An event falls on its date, whatever happens.
