I have been trying to send push notifications to my test mobile app and I cant receive them at all. Although I can see that my device contact has been created in All Contacts..
My test mobile app is not in play store, it is just running on my phone. I have provisioned my app using FCM and received the Server key, Legacy Server key and senderid.
And I am not sure which Id to use while provisioning the app under GCM Client field in the marketing cloud app center. Please let me know which Id to use under GCM Client? Does the mobile app need to be in app store to test notifications?
