Last seen shows the year for a screen that went offline in an earlier year
An offline screen last seen in an earlier year now shows the year in its Last seen date, so a screen that has been dark for years no longer looks like it went offline last week.
Once a screen has been offline for more than a day, its status reads like "Last seen Sep 28, 3:14 PM". That looks the same whether the screen went dark last week or 6 years ago, which makes the screens that stopped long ago hard to pick out, especially if you've just taken over a company's screens.
A screen last seen in an earlier year now shows the year in place of the time: "Last seen Sep 28, 2020". Dates in the current year look as they did. Hover over any offline status, on the Screens page or a screen's own page, to see the full date and time.
