The multi-device synchronization feature ensures that a user does not see the same notifications repeatedly across different devices. It keeps track of read/unread status for notifications, preventing the same content from being shown multiple times to the same user, even if they log in from various devices. You can set multi-device synchronization by enabling the multi-device synchronization feature in settings.
Enable Multi-Device Synchronization:
Go to your Beamer dashboard.
Navigate to Settings > Widget.
Under Button and Trigger, enable the “Enable Multi-device synchronisation” button
Note:
Ensure that your application populates user_id with a unique identifier for each user. This helps prevent confusion between different users sharing the same account.
Ideally, the user_id should be consistent and unique for each user across different devices and sessions.
