Over the last few days when I have tried to delete a video from my playlist on YouTube (on both my iPhone and iPad 2) I get the error "YouTube not available" and the video does not delete. Other aspects such as search and viewing seem to work fine...just can't delete of fo the playlist. Is this happening for anyone else? I'm using firmware 4.3.3. Is this problem showing up in 4.3.5 as well?
