Thank you for posting to the Telerik Developer Forums and for reporting this.
Indeed, I managed to reproduce the issue with the AppBuilder-compatible version of the plugin available in the forums. It is probably correlated to the build phase against the experimental version of Cordova available in AppBuilder. We will need some time to investigate the issue on our side. However, we cannot commit to a particular time-frame for the resolution.
I will update this thread when there is some progress on the matter.
Please, let me know if you have further questions.
