- De-install the app completely if you’re having problems.
- Download it again from Google Play.
If this doesn't help, please let us know about it. Include in your message:
- Which Android device you’re using
- which Android operation system version you're using
- which version of the app you’re using
You should inform us too whether or not your device has been rooted (if you don't know what this means, then your device will most probably not have been rooted ;-))
