In EMM 1.1.0, these configurations (Type of notification, i.e., Local or
GCM) used to be stored in the registry. The default value is stored in the
config file which is then copied to the registry (tenant space) when the
tenant admin logs in for the first time. Therefore this setting can be
changed per tenant. When the device registers to the system, these values
are sent which is persisted in the device. AFAIR the same issue mentioned
by Milan was there in the previous version wherein the Notification Type
gets cleared from the device when it is restarted and Kasun fix this
(Please correct me if am wrong). To add to this there was a limitation in
the previous version is that after a device is registered and if we change
the Notification Type in the server, it does not get reflected in the
device.

Nira
