I just upgraded to 7.6. I have a custom URL category called iTunes that is allowed for a few users. I had one of them tell me that they are being blocked trying to download iTunes. The URL of the download is "http://www.apple.com/itunes/download/". If I run the URL Category check, it tells me it is in the iTunes category I created. However, if I run the Test Filtering, it tells me that the result is "Security Override Blocked" and that the URL is actually in the category "Freeware and Software Download" (which is blocked for all users).
Why didn't the recategorization fix this issue? What can I do to allow this for my users?
