This one is weird: the official Bing app has disappeared from all the App Stores except for the US one since Monday. If you search for it in, say, the Italian App Store or the Brazilian one, the application isn’t there anymore.
There’s no official statement about it, but we remember Microsoft said something months ago regarding the fact that they didn’t want the app to be available worldwide, as it’s been for 3 months now. They left the app for 3 months in the App Store, and now it’s just gone.
We’ll keep you posted about this.
