No Data in hybrid apps

Hi Experts,

I've tried to set up an app based on SDN tutorials for app update nad for push notifications. And my problem is that the apps don't get any data from the backend service. I tried it from our on permis system, and with the NorthWind odata provider but I dont get any data. I use the Kapsel Logon plugin in the apps.

Any ideas about what I'm doing wrong?

Thanks,

David
