Edward, thanks for the heads-up. It sounds like you can reproduce the problem related to Bing. Do you have a support contract? If so, we would greatly appreciate it if you can open a ticket so this gets logged. Will that be possible?
This would be very helpful. Support can enter the problem along with your device OS and any other dependencies in your application.
In regards to support for Fragments, there are several open items for the core team to investigate.
