Migrating to version 3.0.0

In AppMetricaPush 3.0.0, the storage mode was removed. Now only direct mode is supported: the Push Notification Service sends information about the push notification to the extension without storing it in the App Group.

Changes

1. If you use a Notification Service Extension, you must configure an App Group for AppMetrica so that it can share its identifiers between the app and the extension. Follow these instructions.
2. AppMetrica must be activated before using AppMetricaPush in the app and the extension.
3. [AMAAppMetricaPush setExtensionAppGroup:] is deprecated and only needed to send stored events. Do not confuse this App Group with the App Group for sharing AppMetrica identifiers from paragraph 1.
