Last Sunday when I got my new 1520 I downloaded the WPCentral app and updated to the 8.1 preview some time later. I noticed that I'm unable to share an article using twitter although I was able to before on my 900 with 7.8. I tried to look through the phone settings for settings on apps that can share, but there wasn't any. Is there any way I can enable sharing with twitter with the WPCentral app?
