Second push notification is not visible in Android


I am trying to generate push notifications using Cordova plugin. It is working fine in iOS but in Android when one notification is visible, unable to fetch the second notification(I am getting the second notification but not visible). When I searched for the same issue, they told me to increment the notification id in the server, but there was no result after updating it.
Please suggest me a fix

Thanks in Advance.

Could Anyone please share this answer??

Can anyone please update me on this?? Is there any way for implementing second Notification??
