As the application gets updated on the server, the local Citrix app must be refreshed to get the most updated version. If you get an error message that the app is unavailable, unable to connect to the server, or Unable to launch due to internal error it may be caused by an outdated/stale app. The following steps can be used to refresh the apps and resolve the issue.
In the lower right-hand corner of the screen next to the time, click on the upward arrow to show the hidden icons. Then click on the Citrix icon to load the workspace app.
In the top right-hand corner of the Citrix Workspace app, please click on the down arrow next to your username and click on the “Refresh Apps” button. The icons may disappear or turn grey but they will reload after a minute or so. Then, relaunch the app.
