For those who have updated to Kit Kat and are on exchange servers with pin requirements for corporate email, does trusted bluetooth now work as advertised? I have a Sprint Moto X and use exchange with my work email. The exchange server enforces a pin requirement. When I first got the phone, the trusted bluetooth option was greyed out and did not work. When the Nexus 5 was released, I side loaded the new stock email and exchange services apps. I just realized today that I can now utilize the trusted bluetooth option. I'm not sure if the trusted bluetooth option now has been fixed in the Kit Kat stock email app rolling out to the Moto X or if it is an anomaly in the early release Kit Kat email app. Any help would be appreciated. Thanks.
