Update AltoSignal.

Automatic updates are per device, not per account, so one screen can sit on an older build for weeks while the rest of the spa moves on. The usual causes are a device rarely on wifi, a store account signed out on that tablet, or automatic updates switched off for it. An out-of-date screen keeps paging normally, so there is nothing to fix in a hurry. If one will not update at all, tell us and we will look at it with you.

Two exceptions to all of that. In a browser, reload the page; if it still looks the same, hold Shift and reload once more so the browser fetches a fresh copy instead of the one it saved. And the Mac and Linux apps do not update themselves yet, with no prompt when a new build is out: download the current one from our apps page and install it over the old copy.
