Welcome,
There is no issue with the new version which causes only null hypotheses, so this is liable to be an issue with the upgrade process. Please check out the post Please read before you post – how to troubleshoot and provide logging info here so you can see how to turn on and share the logging that provides troubleshooting information for this kind of issue.
Another good first step would be to try out the sample app (on a real device of course) in order to see that it works, or alternately a new app made from the tutorial, and then compare with your app (also on a real device) and see what is different in the setup.
