Custom extension (package) not deployed to Web Player

I am trying to deploy a package to a deployment area "TestDownloadFocusedData" (copy of Production). The package's "Indended client" is set to "any" so should be available to the WebPlayer. I have uploaded my package to the "TestDownloadFocusedData" deployment area and switched both the Spotfire Server's and the WebPlayer's "Deployment area" to my test one:


However, that does not seem to be doing anything as when I open my WebPlayer I still cannot see my package (i.e. it's supposed to be in the Context Menu, when I right-click on a visualization).

Note: I noticed that this text appears when I select my Web Player node:

Does the above mean that I have to apply the update? If so, where I can do that?
