The multicast_id is just a confirmation that your request has been accepted by the FCM server. Possible issues why push was not received on some devices:

  1. Device offline in the given ttl
  2. App was force stopped by the user/battery saving app/launcher customisations like MIUI, OPPO color OS etc
  3. User un-installed the app. Google at times is not able to able to mark the user uninstalled immediately.
