I also had issues (none of my apps could register to GCM) with microg GCM and could solve it by doing this:

  1. Delete cache and data of microG Services Core and reboot.

  2. Activate Device Registration in microG and reboot.

  3. Activate Cloud Messaging and reboot.

  4. Delete data and cache (or reinstall) of apps that should use GCM and start them.

  5. It worked.
