GCM IOS NotRegistered issue

Question

I've been using GCM just fine for a long time already. One day it suddenly broke. The problem is that the first push I send I get success status back but the app doesn't receive any push whatsoever. The second push I send gets failure with an NotRegistered error. I reinstall the app: success(no notification received), failure(NotRegistered) -> Loop. I don't know what's changed. Google support is being very unhelpful and is taking a lot of time answering simple question whether it is GCM problem, APNs problem or client problem. If anyone had such issue before, please let me know what to look for. That is how it looks like:

I suspect that it happened after updating to iOS 9. I'm not sure though. If there are things in new iOS that might be blocking GCM I would appreciate if somebody pointed it out.

UPDATE:

GCM push fails with NotRegistered

that guy had a similar problem. The issue was with some manifest file. Could there be some entries in the Info.plist that I need to add for iOS 9 to allow GCM ?

UPDATE:

onTokenRefresh is being called every time the app launches. I'm getting the same token back, though. So there is a problem with a token on a GCM server, I suspect.

        // This works only if the app started the GCM service
        GCMService.sharedInstance().appDidReceiveMessage(userInfo);

        // Handle the received message
        // Invoke the completion handler passing the appropriate UIBackgroundFetchResult value

        handler(UIBackgroundFetchResult.NewData);
        // [END_EXCLUDE]
}

UPDATE

OK, so I believe I messed up with .plist location (it wasn't in the root for some reason). I moved to the root and now I'm getting this warning/error when starting GCM:

UPD. Okay, it actually happened only once and stopped. So I don't think the problem is here.

After I moved .plist to the root directory onTokenRefresh() calls stopped, but I'm still getting NotRegistered.

Answer 1

So I solved the problem. It appeared that I was not using the right iOS Development Provisioning Profile. I was using a generic one, while I needed to use a specific one for my bundle name. The reason it happened was because I reinstalled my OS a week ago or so, so the other certificate was wiped out and didn't work until I downloaded and manually added it to Xcode. I also needed to delete the team provisioning profile from the device as well. Totally not GCM or APNs fault.
