I followed the Steps of Activation.
- Created a project on the FCM Console,
- Copied the Api Key and past on the Emm Admin
- Copied the Sender ID and past in the mobile agent App
- Begin Enrollment of the Device.
The Device stays on the enrollment screen and the error is RegID not found. After Exit and restart the server I get this error
ERROR {org.wso2.carbon.device.mgt.mobile.android.impl.gcm.GCMService} - Exception occurred while sending the GCM notification : "registration_ids" field cannot be empty
