Hi, I have the problem on my Curve 9320, but after much searching around, I have found at that there is a problem wit the Youtube app which the developers are working to fix.. The app should be back to normal by the end of this week, in the meantime, there's nothing we can do
I have now the same problem. And i've tried everything (hard reboot, change language as you suggest, update). Nothing, I can't solve the problem. It seems html5 software/driver disappeared. I can't click the play button in youtube mobile or they say i have problem with my browser that doesn't recognize any video format using the desktop version. I'm in italy.
