Please note that iOS 8 requires more permissions to allow the app to use the camera of your device. To check it out on your device, please go to:
Settings > General > Restrictions > Camera > Angry Birds Star Wars II > On
and then you need to also allow the app to use your camera via Privacy by tapping on:
Settings > Privacy > Camera > Angry Birds Star Wars II > On.
That should do it! If you are still having trouble with scanning your Telepods, please submit a support request by clicking here.
