I have a user who is using an app. My app sends push notifications for certain events. This particular user does not have a Google Play subscription -he sideloaded my app.
When the app starts, the app is able to generate a push token for his device. However when my server sends a push, his device does not get it.
I've searched around, and I've seen threads which talk about requiring a Google account for "sending" a push - but my question is for receiving. The fact that it is able to "generate" a token during registration is confusing, if Google was planning not to route GCM messages to the device.
Thanks.
