So when I share a YouTube video and enter a letter in the "To:" heading, it shows me a listing of all names beginning with that letter. My problem is that I had the incorrect email address for a name and have since corrected it but I am still shown the incorrect listing, along with the correct one. It seems to use information from contacts and email, even when they are deleted and no longer in the iPhone. Is there a way to clear the cache for this so I am not shown the old stuff? I can't find a way to do this in my iPhone.
