Problems with Shazam and Youtube
 

I have a 9520 and I have installed Shazam a couple of months ago.
It has been working well but recently when I try to tag, I get a message
"Failed. Unable to connect to the internet". I can connect and download from other internet web sites and also Shazam works well if I connect via Wifi
It seems to be a settings problem but I don’t know what to check.
Also Youtube doesn’t work, but when I connect via Wifi,it works very well

Have you tried a battery pull?
