I cannot see the 'Update' button to upgrade SAML SingleSignOn for Fisheye/Crucible from version 2.4.7 to version 2.5.9. I have also tried installing the app from a downloaded .obr file via the marketplace but that did not install (it just hung on installing).

We are on Fisheye/Crucible version 4.8.1 (Server). Does anyone have any advice on how I can upgrade SAML SingleSignOn for Fisheye/Crucible?
