Hi,
Try first with a new empty project and make sure you have an app bundle identifier that is new.
Let me know how it goes. when something is not working like that, it's best to isolate in a dedicated project, to test just this feature, then if it works there, the problems lies within the integration and not the feature itself.
if it doesn't work on a test project, share that project with me, I'll give it a go myself locally.
Bye,
Jean
