Cordova app doesn't work properly with Windows 8.1 update 1

Hi guys,

We've developed Sencha Touch apps with Cordova in iOS and WP8.1. Everything seems to be ok before we upgraded the WP to WP8.1 update 1. Since then back button of navigational tab cannot be pressed. It shows in the app fine but when I press it nothing happen. I checked and it seems like the button doesn't get pressed at all. Also it's very laggy........

Is anybody having the same experience?

We are using Sencha Touch 2.4 with Cordova 3.6.3 for WP 8.1 app.

Regards,

Pan
