There are number of posts explaining how it works however all assume your OneSignal account is correctly set up and successfully tested.

I got it to work… what I have to do:

- regenerating the p12 file, using OneSign Provisionator;
- edit the app profile at Apple Developer Panel;
- download new .mobileprovision file;
- in OneSignal settings, replace the .p12 file;
