How to create track read message in app android and iOS (xmpp framework) Help me please !!!
there is no support provided by any client to track your read report because it completely client base activity you must handle manually you can define your own extension to make it happen.
The extension which handles “read” messages is https://xmpp.org/extensions/xep-0333.html
The semantic of “read” maps to the “displayed” element.
