Five labels used to apply themselves to screens: Landscape, Portrait, Full HD, UHD and Anywhere. Screenly maintained them from each screen’s own properties, which meant you could not rename them, delete them, or decide which screens carried them.
They were not describing screens well enough to earn that. Four of the five stood in for properties a screen already reports, and a fixed set of resolutions cannot represent what people actually run: a display that is neither Full HD nor UHD, which is a great many of them, got nothing useful from either label.
The groupings were also rarely what anyone wanted to target. Every portrait screen, or every Anywhere screen, spans different sites, rooms and purposes that have nothing else in common, and usage bore that out. Almost nobody scheduled anything against them.
So they are ordinary labels now. The ones in your workspace keep the screens they were on, and you can rename, delete or apply them like any label you made yourself.
If a playlist plays on one of these labels: it now plays on the screens that carried the label at this release, and that set no longer updates by itself. A new landscape screen will not join the Landscape label on its own, and a screen you rotate will not change labels. Check any playlist that targets these five, and either maintain the label yourself or assign the screens directly.
If your workspace already had its own label with one of those five names, the two are now a single label holding both sets of screens.
Targeting content by a screen’s own properties, rather than through a label standing in for them, is what we are working on instead.
