Push not sent

[LaBrie13]

I'm doing a simple
Push.message("New score created", where={"deviceType": "android"})
which is working fine. It puts the notification into collection _PushStatus.
But the message is never sent to the clients.

I am using a self hosted server, which is started with the senderID and apikey from GCM.
The client is registered with ParseInstallation.getCurrentInstallation().saveInBackground();

I think I am missing something essential, but I am stuck so I hope you can help.
Thanks in advance.

I have personally never used parse-server for pushes, so I'm not sure what the support is support to be like here. This might be a question for the parse-server repo -- tell them you're inserting into _PushStatus via the REST API.
