IMHO, there are some deficiencies with the My Apps page.
In my experience apps do not appear on that page if the user has non-accessed the app with his last 30 days. Users basically will never click on the advanced search so they open up an internal support ticket, saying they do not have access to an app when in fact, the problem is they simply cannot find of the app on their my apps page.
I have a Client, which literally has 100 apps. So what we did is we use one of the options for a connected table to auto generate a list of all of the applications in an app.
Then we put a branding item, globally at the top right of every page which provides them with a link to get to that list. Then we can just tell the users if they are having trouble finding an app that can go through that list and easily see a list of all applications that exist, even applications, they do not have access to.
I'm not sure I have experienced the 30 day app hide. However, I think I am having success if I provision a user, adding him to a group, rather than adding the user to the group AFTER the first time they log in. I'm not exactly sure, and it is so incredibly difficult to test for. However, between SSO, and Provisioning and groups, sometimes the user can see the app and sometimes they can't, and for the life of me I can't figure out the specific rules for the specific combinations.
