When a label is not working

A playlist targeting a label and reaching nothing has a short list of causes. Work down it.

A playlist that looks correct and plays on nothing is nearly always one of these.

1. The names differ

The commonest cause by far, and the hardest to see. Read both character by character.

warehouse and warehosue look identical at a glance and are two labels. So is a trailing space, and so is plant floor against plant-floor.

Find the label on the Labels page and check how many screens carry it. If it carries none, or the playlist's label isn't there at all, the label on the screens is not the label you typed. Two near-identical names sitting next to each other in that list is the giveaway.

2. The screen does not carry it

Open the screen and read its Labels tab. It is faster than reasoning about it.

3. The playlist targets something else

The playlist's Screens tab lists every screen it reaches, however it reaches them. If the screen is not in that list, the assignment is wrong regardless of what the labels look like.

4. The label is right and something else is wrong

Labels only decide whether a playlist reaches a screen. If the screen is in the playlist's list and still shows nothing, the cause is further along:

Is the playlist enabled?
Is its schedule active right now, in that screen's local time?
Is the screen enabled and online?
Has the screen finished syncing?

How a screen decides what to play is that list in order.

The check that settles it fastest

The Playlists tab on the screen lists every playlist assigned to it, including disabled ones, and its Assigned via column says how each one gets there. If the playlist is there, labels are fine and the problem is elsewhere. If it is not, it is an assignment problem.
