    Today I received Hotfix-BIGIP-17.5.1.6.0.24.25-ENG regarding the missing virtual servers in the GUI. They also stated that it should fix the AS3 issues. It did not.

    So I'm still waiting ...

        Meanwhile I got the same hotfix that does not fix the AS3 issue. I further escalated the ticket.

      Hi. Exactly the same check today . Also told F5 support that their fix on admin users /gui on non Common partition has nothing to do with AS3 issue. HF 24.25 includes only : 

      <hotfixID>ID2264009-2</hotfixID>

      <hotfixTitle>Admin users cannot create or view virtual servers and other objects in non-Common partitions in TMUI</hotfixTitle>

      </hotfix> , and that has nothing to do with AS3
