Are analytics needed to get FCM working?

Fung5 years ago

Hi,

I try to get FCM working.
I managed to get the server key into the settings and the google-services.json into the app. When I login with Traccar Manager the user gets the notificationTokens attribute.
When I trigger test notifications I get the web and the mail notification, but no push notification. When I try to send a test message from the firebase control center (the web interface) it shows this error or warning: "Unable to reserve a user property for Notification conversion funnel analysis" so I was wondering whether analytics are needed for FCM to traccar?
I can't even send test messages to the app on my device ...
Myabe someone could help me debugging this?
