Just got myself an iPad and noticed that the advanced search filter option is missing on the YouTube mobile web app. Therefore you cannot search videos by date. This option is available on the iPhone but not iPad ??? I have tried the Cydia app ProTube and the filter option is missing as well. You can go to the full desktop YouTube version via http://www.youtube.com/?nomobile=1 via Safari but none of the videos play even when enrolled on HTML5. Same problem with Chrome for IOS. Can anyone recommend any better Apple Store apps or Cydia tweaks with advanced search capabilities. Many thanks.
