Push notifications not sending with test despite having APN & specific device FCM token

[broskees]

I've looked all over stackoverflow and google for an answer to this, these are some of the things I've tried:

• Following Google's Client and Receive Guides.
• Made sure firebase has proper APN settings.
• This stackoverflow answer.
• This stackoverflow answer.

I'll run through what I've got:

So basically I run the app, fetch the FCM Registration Token from the Console, as so:

Then I add the token to the Notification Center and try a test send, as so:

You can see from the reports, none of the notifications are being received, as so:

Not sure what else to try. Thoughts?

[mikehardy]

I find that my notifications are received, but not reported well in the web console.
Do you find the same? Or are you relying strictly on the web console to verify receipt?

@mikehardy

Well they should be appearing on my iPad too correct? Also, I'd think the "Message ID" should be showing in the XCode console as well, right?

[mikehardy]

Every install is a different token (tokens are hooked to "Installations" firebase module which we do not explicitly expose via APIs here but is used by all firebase modules that address devices). So you'll have to specifically address an iPad token for it to show up there. You may already be doing that. Unsure on message id showing up in xcode console, I think you may have more info with firebase-ios-sdk debugging turned on (it's below our layer - firebase-ios-sdk documentation should be consulted on how to turn it on but if I recall it's a flag you set in Xcode on build scheme, I vaguely remember it as FIRDebugEnabled or similar, if searching our issue list or their docs for it)
