I have only recently started using GameSparks so sorry if this is a stupid question but I can't find the answer?

The Problem:

None of the players registered for push notifications are receiving notifications when their scores have been beaten in the game?

My Goal:

I would like to have players who have registered for push notifications be alerted when a player posts a new score higher than their own and as such lowers their rank.  I would prefer all of these notifications to be sent via push notification if at all possible to encourage players to return to the game if they have been beaten.

What I have set up:

I have several android devices registered for push notifications via Firebase (All using Device Authentication).

I have two leaderboards one for global scores and one for country based scores.

The devices are submitting scores to the leaderboards and I can see them via the NoSQL interface.

When a score is submitted I display the current rank to the player in game and all this works great.

I have set the GlobalRankChangedMessage to be push only in the configuration.

But still I can not see any push notifications on the registered devices?????

In the documentation it states the following about the GlobalRankChangedMessage 

"This message is sent to players when their rank in a global leaderboard changes such that they are knocked out of the configured 'Top N'."  Is there somewhere I need to configure what the Top N is for my game????

What I have already tested:

• Submitting scores to the leaderbords works fine and if I retrieve the rank form the server it is returned correctly
  
• I have tested that Firebase is configured correctly using an event with some Cloud code and can successfully send test Push notifications to the devices from within the test harness.
• I have changed the message settings for the GlobalRankChangedMessage to have sockets on and sockets off and push only and this does not seem to make any difference.
• I tried setting the FCM JSON Template (Advanced) in the GlobalRankChangedMessage to what is used in the documented Firebase config documentation.

Can anyone give me some advice about what I might be missing?

Is there something I need to do to fire off the Rank Changed Message?

Does it only fire once a day or once a week?

Any help is much appreciated

Thanks Liam that was the problem.  When I set up my leaderboards I used the Unity Leaderboard tutorial for setup and the notification fields are not really discussed in that tutorial but are covered much better in the generic leaderboard documentation.  I should have followed the more details link.
Just in case others find this post the Link you provided Liam might be wrong I found the info here based on your answer.
Thanks for your fast and helpful response.
 

 

I am having issues with the GlobalRankChangedMessage as well. I configured using Firebase and can receive push notifications on both iOS and Android. However, when I try and get the global rank change message to fire, it is sending 2 messages. One message is correct (this message is coming from a script in cloudcode under User>GlobalRankChangedMessage. The second push notification only shows ${data.title},${data.body}

Which is what is configured in the advanced section of Messages>GlobalRankChangedMessage

Should I remove the script from cloudcode? If so, how can I properly configure the standard Message for GlobalRankChanged?

Or is there a way to ONLY send code from the cloudcode script and not have the standard Global Message send?

What I have tried:

- adding a script to ScriptExtensions (but it may not be configured correctly)

- removing cloud code script attached to the User>GlobalRankChanged (this causes only the ${data.title} message to send)

I resolved the issue by turning off the standard GlobalRankChanged message and only using the message in CloudCode. :D
