The database has rebuilt and the app still crashes my ps3 in the same way before, well now I'm going to wait because a lot of people are having this issues too, maybe the developers are trying to fix the app for us. At least I hope so. I'm really upset :/
I hate this app so much. First off, you used to not have to sign in to go onto Youtube, because it was on the web browser. Now you have to sign in so if you have problems with PSN at the time you can't even get into Youtube. Second, it's glitchy as h*ll for some systems, including mine. Sometimes it works, 2/3's of the time it doesn't load, freezes my controller so all I can press is the PSHome button, and when I try to force quit it, it 3 beeps me and shuts off. Can't be good for the system. Third, the search is the slowest, like literally you couldn't make a worse search engine format if you tried. It not only takes a thousand hours, but the so called 'predictive text' feature is hard to use, and when you type a letter it doesn't stay on that letter, it automatically goes back to the middle of the alphabet, confusing and disorientating you so you type the wrong letters. Fourth, Youtube XL (the old Youtube) used to show you 5 videos at a time when you searched something, this new app only shows you three. The only good thing about this new app is that if you are somehow a wizard who can manage the sorcery needed to actually watch a video on it, the quality is better than the old Youtube. I don't think it is worth the hassle though. I would gladly deal with a little pixilation for the old Youtube back. Just saying.
I think many of you that are having problems are do to your internet connection or the file not downloading right, try deleting the one you have then downloading it over again.
My youtube app is working just fine I've had no problems with it at all, maybe check and see if you have the newest firmware 4.21 and not 4.20....
