Reload the page. This happens when a tab has been open since before AllDone was updated: the page then asks for a piece of the version it started with, which is no longer there. AllDone notices and reloads once by itself. If that does not fix it you get a page headed "Something needs a refresh" with a Reload the page button.

The application is delivered in pieces that are fetched as you move around it. Each release gives those pieces new names. A tab that has been sitting open all morning, or overnight, still holds the old names, so the next screen you open asks for something that has been replaced. It is not a fault with your job or your data.

The most common version of it is coming back to a tab you left, clicking through to a screen you had not opened before, and finding it blank.

It watches for that specific failure and reloads the page once, from the server rather than from the browser's cache, which picks up the current version. The reload is deliberately once only: if the same thing happens again within a few seconds, it stops, so you get a real message instead of a page reloading in a loop.

If the reload does not take, the recovery page appears with the explanation and the button. That is the point at which to click Reload yourself.

No. Decisions are saved when you record them, uploads are stored when they finish, and a run is executing away from your browser, so a reload does not interrupt it. Come back to the job and it is where you left it.

If a blank page keeps coming back on the same screen after a full reload, that is worth reporting: it is no longer the release explanation.
