I just updated my iPad 2 to iOS 8.1 and some bugs were fixed by this upgrade, but a new one has started. I have Xfinity Home as an App which allows me to monitor my home security cameras through my WiFi. It worked fine until I put in iOS 8.1. Now it tries to boot but just briefly flashes the home page and the goes black. I've tried deleting and reloading the App several times with same results. Any ideas out there?
It is probably a bug that needs to be fixed by the developer of the app.
