App not available despite being approved/enabled in app marketplace admin

[Mark_CSU]

Despite the Aborb app being approved by admin (me), the app is not available to users in desktop client, nor does the app appear in the added apps list or apps on account list.

Hi smart people!

App is enabled for specific users.
Once noticed that the app was not available to the specified users, I added myself to the list of users approved for the app as well as a secondary test account.

-Neither my own account or the test account are able to access the app via the desktop client.
-Both my account and the test account are running the latest version of the client (6.2.3)
-Further, when the Absob app is searched for using the “add apps” feature in the client, no results are seen. (See provided screen capture)

Thank you in advance for any replies and thoughts/idea on what issue could be.
