I am having the same issue. Please revert the app to previous version.
It's a great idea, but the problem is how to reinstall the previous version of iOS Bing...
As far as I know, that's not possible - apart from the gigantic procedure of restoring the iPhone to a previous backup...
Or is there another way to do it?
For this to work, Microsoft would have to restore the previous version in the Apple Store and, at the same time, users would uninstall the app (with the serious error or bug) and then install the "new" version that Microsoft would make available under the terms just mentioned (ie: the version before the update on the 10th!)...
Friendly greetings!
Miguel Frederico.
