My question seems to be quite simple...
In a Journey, how can I create a split between:

* those who are able to receive a Push Notification
* those who can't (and they'll receive an email)

I don't know what data I would have to check. I thought I would use a dataview which would allow me to update a field in my Contacts' Data Extension but I can't find it neither.

Could you please help me ?

Thanks in advance !
