App store hide/unhide problems: (1) can't "unhide" (2) "hidden" apps don't remain hidden

Question

I've searched hither and yon online for a way to “unhide” apps I’ve hidden in the App Store. The procedures I’ve been able to find, involve choosing “View Account”, logging in, and selecting an item called “Unhide Hidden Apps”. This would seem straightforward enough except that, I find nothing for “Unhide Hidden Apps”. I’ve tried on both my iPad and my iPhone, both running the latest iOS.
Then, to add to the frustration, this. I select an app in the App Store. I slide and select “Hide”. (Say I’m viewing the set “All”.) Then I select “Not on This iPad”. The supposedly “hidden” app is still visible. Okay, what the heck? I slide and select “Hide”. Then I select “All”. Guess what? The app is still visible. I select “Not on This iPad”. The app is still visible. Not fair. :-(

Answer 1

You are right. They do not all show up there - I'm thinking only those that are actually downloaded to the Mac maybe?
If you go to the Quick Links section in the iTunes Store, and click on Apps and All, you should see both the downloaded and the iCloud ones on that list. (make sure you have also click on "All" and not on "Not in My Library".
And if you hover over an app on that list, you will see a little "x" in the top left-hand corner. Clicking on that hides the app. You can hide both apps that are downloaded as well as those still in the cloud. However, it does not remove it from your device. If you did hide it in iTunes, and then also deleted it from your device, it would then be fully "hidden".
Does that make sense? (I still can't figure out how to do the Hide thing on my iPhone.... )
