Push Notification FCM on Meteor 2021

Did you activate debugging for activitree:push?

yes, in CordovaPush.Configure debug is set to true.
wait i think i found the problem…
no, i found a problem but now I am back to things not working without error messages + mac os 11.3 killed my android emulator (ios development still fine, thank god)

Ah ok, I only thought I had debugging enabled on the server (I had added the debug: true in the Configure options just like you do on the client). So I got proper debug logs now and the problem seems to be an Auth error.
