57 |(% style="border-color:white; width:912px" %)In the Loymax Smart Communications interface, you can configure whether to send messages to all existing push tokens associated with a customer or only to the token most recently added to the database. Other devices will be ignored in the latter case. By default, the setting is **To all devices**.
