The license pool

One pool per subscription, shared across linked workspaces. Reading the workspaces table, and exporting it.

Your licenses are a pool rather than a set of permanent tags. Connecting a screen takes one; disabling that screen returns it.

Across linked workspaces

On Enterprise, linked workspaces share a single pool held by the parent. A license one team is not using is available to another, so a group of regions or brands draws from one set rather than buying separately.

The Screen licenses count on a parent workspace's billing page includes screens in every child, not only its own. A parent showing more licenses used than it has screens is normal.

The workspaces table

In the parent, go to Settings > Billing & subscription > Workspaces on this plan. There is one row per workspace with its name and how many licenses it is using. Sortable by either, and searchable, which starts mattering past a dozen.

Rows are labeled. Parent marks the workspace that owns the subscription. Current marks the one you are looking from. A workspace can carry both.

Exporting it

The export button above the table gives you the table as a CSV.

That is the quickest answer to why a pool is full, and the thing to attach when asking a group of teams to give some back. Sorting the export by licenses used names the two workspaces holding most of them in about ten seconds.

Rebalancing

There is nothing to reassign. A license is not allocated to a workspace in advance; it is consumed by connecting a screen and released by disabling one.

So freeing licenses means disabling screens somewhere, not moving quota around. The export tells you where to ask.
