My problem is - I want to send a push notification using a journey, but I can't get the ContactKey of a MobilePush contact and admit it into a data extension (it doesn't exist in the _PushAddress data view).
So my question is: is there any way to get the Contact Key of a MobilePush contact in order to use it in a data extension as an entry source to a journey. If not, is there any way to send a push notification to a contact based on his ContactID (ContactID does exist in _PushAddress).
Thanks in advance to all the contributors.
